Did I mix it up with currency conversion? CLEAR: lv_length. But a primitive property for an amount does not make sense without reference to the currency. Add a Comment Alert Moderator Vote up 1 Vote down Former Member Dec 05, 2006 at 07:14 AM Hi, Please use the following FM. ENDIF. But where does the currency code come from? lv_amount_2 = lv_amount_1. Data Formats and Structures. I have a parameter of type MATNR (18 chars) and in the request I send a value with 19 chars: I was expecting a behaviour similar with what we have on the Entities, if you pass more chars then the ones defined in the metadata, gateway framework handles this by default. I will create a blog on this one for future colleagues. FUNCTION z_currency_conversion . The reverse is also not possible. This is equivalent to the built-in data type P (packed number). If VBAK-WAERK contains EUR, the JSON response is shown as: If VBAK-WAERK contains JPY, the JSON response is: Please observe that the 2 decimal places in the backend are not interpreted as such. CURR with the length 31 and 14 decimal places. ABAP developers may know about the possibility to connect an amount with the corresponding currency field in the ABAP dictionary: In the first blog post of the series, we looked at how conversion exit information in the ABAP dictionary is used in SAP Gateway Foundation through structure or property binding. Use method SET_UNIT_PROPERTY at the property that represents the currency amount. Clients might need the information which property X contains the currency for a given property Y that holds an amount. We then define the selection parameters such as the date range for sales data. The intermediate result of the conversion is rounded to the end result using commercial rounding; otherwise, it is truncated. They are not permitted as key properties of entity types. must be passed as a parameter. At this point in time, the formatting is done using function module CURRENCY_AMOUNT_SAP_TO_IDOC. Hence, your service will not show the relationship and the SAP Gateway Foundation framework will not use it for amount formatting. The Function Module AIPB_CURRENCY_SAP_TO_EXTERNAL (Convert currency amount and code from SAP into external format) To repeat: the result is a string with the formatted currency amount. which can extract sales order data from SAP. At this point we can hang the converted file with the FM SAP_CONVERT_TO_CSV_FORMAT to lt_file. We then define the selection parameters such as the date range for sales data. The information will be evaluated by the OData library implementation when the parameters are transferred to the Gateway framework implementation. This allows you to see the coding differences/benefits of the later inline syntax. On occasion, a deviating number of decimal places is required to specify prices, for example, at German petrol stations the price per liter in EUR has three decimals to the right of the decimal point. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8). Rates might not be available for currency pairs, and so on. For other SAP HANA databases, replicate the . Investigating the reason I saw that in the versions of SAP I use there is a comment according to which the standard FM does not manage the possibility of inserting a header line in the .csv file. thank you very much for this detailled explanation. The value passed is rounded to two decimal places before it is converted. The automated service metadata determination described in the previous section looks precisely for such a configuration. a prerequisite for the example, the units and their conversion rules must be available in the corresponding database tables. In ABAP-based SAP software, currency information is stored in the TCUR* tables and it makes sense to handle the described formatting in the backend. (sorry, it's been a while since I wrote in abap). But with the OData version 4.0 stack the complex annotations are created automatically. and is part of the function group AIA_TOOL It will Display 1000 Yen by converting the amount based on TCURX values Add a Comment Alert Moderator The result has the data type This site requires JavaScript to run correctly. Here is an example for an OData version 2.0 service. The SAP Gateway Foundation framework calls function module CURRENCY_AMOUNT_IDOC_TO_SAP returning the value that can be handled in your data provider class. In our example, the unconverted string 123 become a string 123.00 for EUR, and this is moved as 123.00 to the field typed with NETWR_AK. I cannot provide one ad hoc. Or, would you consider 123.00 in any currency or only in those with 2 decimal places? Do you have any suggestion for this case? In OData services delivered by SAP, the maximum length of a currency code property is 5. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8. I forgot to replace, As for using the standard FM, I wrote the following code before the. All rights reserved. As a comparison, the same conversion is also performed These are the IMPORTING parameters of this function module. The output that we get is in the required format. Here's an example code to get started: import pyrfc import pandas as pd # SAP connection parameters params = { 'user': 'username', 'passwd': 'password', 'ashost': 'hostname', 'sysnr': 'system_number', 'client': 'client_number . This function module does not define any TABLE parameters. Whats more, formatting also needs to happen in the backend itself if you think of backend-controlled printing of business documents. Contains the field names of the external BAPI structure. Search for jobs related to Function module to convert currency format in sap or hire on the world's largest freelancing marketplace with 20m+ jobs. In the latter case, the ABAP OData library deserializes the request body into the ABAP structure where the currency amount is stored as a string. Please, To connect to SAP and get sales data using Python, we can use the. without seeing your code I don't know how to help you. In this blog post, we are going to take a deeper look at a very special conversion-related topic: the formatting of currency amounts. The source unit The output that we get is in the required format. is also performed using the function module UNIT_CONVERSION_SIMPLE. In the SELECT list, the following CDS view sets the decimal separator SD_CONTRACT_READ_CONDITIONS- Possible currencies and their decimal places are based on the database tables TCUR of the package SFIB. It just checks whether the string contains a valid value and inserts the formatted result into the XML/JSON http response. I have found the doc Function Import Parameter Length Check but its only for GW ABAP 2020, where here I am at version GW ABAP 7.50 SP17. Two choices for easy smart lighting - Start setting the mood with Hue Smart bulbs and your Echo device, supporting up to 5 Hue Bluetooth & Zigbee smart bulbs. UNIT_CONVERSION( p1 => a1, p2 => a2, ) | CURRENCY_CONVERSION( p1 => a1, p2 => a2, ) Regarding the USE_STRICT_FUNCTION_PARAM_CHK feature, where will it be? Its internal data type CUKY has length 5. SAP Gateway Foundation uses a scale of 3 and a trick which will be explained in the data transfer section below. If we need to convert amount format based on country then we can use the below code snippet to change the format to the particular format followed by any country. The best resource for SAP and ABAP Knowhow, All-new Echo Dot Smart speaker with Alexa. CURRENCY_CONVERSION( p1 => a1, p2 => a2, ) CONDENSE lv_amount_1 NOGAPS. All of that is business functionality deeply embedded into the logic of the different application components. The function CURRENCY_CONVERSION performs a currency conversion for the value passed to the formal parameter amount. FUNCTION z_currency_conversion . *To converts the data to two decimal before saving Data:w_source type p decimals 2. UNIT_CONVERSION( p1 => a1, p2 => a2, ) To know more details on handling the currency conversions, its roles and limitations, please check the ABAP Keyword Documentation. This function module does not define any TABLE parameters. At this point in time, the select options just contain unconverted data. length check on and off? Here, the target unit is passed to the parameter in question. The result has the data type The value passed is rounded to two decimal places before it is converted. By the way, the code above is automatically generated if you create an entity type based on VBAK in the SAP Gateway Service Builder (transaction SEGW). Lets start by shedding some light on those questions. The presentation of currency amounts on a user interface or in print forms must observe those specifications. DECIMAL_SHIFT( p1 => a1, p2 => a2, ). The content of such an ABAP field is transferred into a string when the data is handed over to the internal data container of the SAP Gateway Foundation framework. SAP Business ByDesign, for example, stores currency amounts as decimal floating points (mainly dictionary type DF34_DEC). In any case, the SAP Gateway Foundation framework is fundamentally not able to return select options if two different properties are combined with or (note 1671893). Did I miss something ? I have an issue with Function Import parameters length. You want to see 100 JPY (or 100 ) and not 100.00 JPY but you would like to get 100.00 EUR or 100.000 TND (Tunisian Dinar). Answer is to use the BAPI function designed for that purpose: Data: Result type bapicurr-bapicurr CALL FUNCTION 'BAPI_CURRENCY_CONV_TO_EXTERNAL' EXPORTING currency = 'JPY amount_internal = '10' IMPORTING amount_external = Result. If you would program your model provider class, then the mechanisms will be quite similar. For this we require the currency key and the amount that needs to be converted. Example: For VBAK-NETWR the currency information from VBAK-WAERK is used. You may receive the converted information for a specific property in the table of select options in the following ways: Internally, this method uses a two-step approach. within the package AIP. The value passed is rounded to two decimal places before it is converted. Based on the specific internal metadata settings, the ABAP OData Library can handle this string information in the context of the Edm.Decimal property. CONVERT_AMOUNT_TO_CURRENCY Convert an amount from a currency to another (exchange rate taken from database tables) CONVERT_CURRENCY_BY_RATE Convert an amount from a currency to another, according to the passed exchange rate BAPI_CURRENCY_CONV_TO_EXTERNAL Conversion of Currency Amounts into External Data Format value1;part2, value2 should be generated as "value1;part2";value2 (and not value1;part2;value2). The result has the data type CURR with the same technical attributes as the actual parameter passed to amount. Its value is produced by multiplying the input parameter rounded to two decimal places by 10 to the power of two minus the decimal places defined by the currency passed. The following is an excerpt of the program DEMO_ASQL_CURRENCY_CONVERSION. If "X" (default value), the decimal places of the source value are moved as specified by the decimal places of the source currency (see below). The FM SAP_CONVERT_TO_CSV_FORMAT has, in fact, an input parameter I_LINE_HEADER which, if set, would allow you to insert the header line in the file. using different rounding rules from ABAP. A primitive property of type Edm.String with a maximum length of 3 would be suitable. If VBAK-WAERK is empty, a formatting with these 2 decimal places will happen: Tipp: Always test your service with currencies such as JPY or TND. The column AMOUNT has two decimal places, which means To connect to SAP and get sales data using Python, we can use the pyrfc library which allows Python to interact with SAP systems through Remote Function Calls (RFCs). For all currencies according to ISO 4712, the field WAERS contains the alphabetic ISO code, that is, the content of WAERS is equal to the content of ISOCD. In summary, in this post I wanted to share a code that I wrote to get the header to add to a csv file produced by an FM implemented by SAP (since this function module does not manage this functionality). Here, Edm.Decimal only allows for fixed precision and scale. If we need to convert amount format based on country then we can use the below code snippet to change the format to the particular format followed by any country. In the field Function group, enter the name of the function group to which the generated function module is to be added. The SAP Gateway Foundation framework offers a method to retrieve filter information as select options in GET_ENTITYSET methods of the data provider class. The framework updates the service metadata with the information required to control amount formatting. Your UI client must be able to handle that. You may also need to install the. that the decimal places are determined directly by the currencies passed. If we apply structure binding. This is either done by the chosen rate or through table TCURR. Currently, there are only two exceptions: CLF and UYW with a minor unit of 4. The decimal places of the result are moved as specified by the decimal placesof the target currency (see below). For example, $filter=TotalNetAmount gt 123 would still appear as. As it is just a topic of presentation, one might argue that this formatting is UI client logic. The question of how the filter query option is evaluated is strongly dependent on your data provider class implementation. The SELECT statement calls a currency conversion in its SELECT list for the column AMOUNT of the DDIC database table DEMO_PRICES. OData version 4.0 knows the symbolic value variable for the facet scale of Edm.Decimal to express that the number of decimals to the right of the decimal point can vary between 0 and a precision-dependent maximum. on the basis of the client-specific rules saved in the database tables TCUR of package SFIB. To finalize the formatting process, the minus sign for negative values is re-positioned from the end of the string to the front. The implementation framework in SAP Gateway Foundation supports the creation of OData services in an ABAP-based backend. You can use a max length which is even bigger, say 100, but you would nevertheless check in your application code that the payload does not exceed 18 characters. Do you mean the possibility of switching the max. The function module is stored in the Function Builder in the function group you specified. for the column AMOUNT of the database table DEMO_PRICES. Admin; CA-DMS; We have learned that we do require different numbers of decimal places depending on the currency. But how does the framework behave during OData request execution? The target currency must be passed as a parameter. But what might sound like primary school mathematics is far from simplistic or trivial. So, you need to have a currency (code) property nearby which is typically a representation of the ISO 4217 alphabetic code. Currency conversions are now possible in ABAP SQL as well as ABAP CDS. These are the IMPORTING parameters of this function module. In addition to the source text for the function module you can have a blank . The program DEMO_CDS_DECIMAL_SHIFT accesses the view in a SELECT Not Released If "X" (default value), the decimal places of the result are moved as specified by the decimal places of the target currency (see below). ***Convert to internal SAP format CALL FUNCTION BAPI_CURRENCY_CONV_TO_INTERNAL EXPORTING currency = lv_waers amount_external = lv_amount_2 max_number_of_digits = lv_length IMPORTING amount_internal = lv_internal. As a prerequisite for the example, the currencies and conversion rules must be available in the corresponding DDIC database tables. Finally, we close the SAP connection using, Note that the actual selection parameters and function module may vary depending on your SAP system configuration and data requirements. e.g. Thanks for checking out and commenting, Srgio Fraga. No matter how the conversion is made, the same results cannot be expected as when using standard function modules for currency conversion, since these modules are generally less precise and round the intermediate results accordingly. One aspect is known as currency conversion: calculating the amount in currency A based on the amount in currency B with a given currency exchange rate between A and B. ***Convert to SAP external format WRITE lv_internal TO lv_external CURRENCY lv_waers. Target currency from column WAERS of the DDIC database table TCURC. SELECT SINGLE dcpfm FROM usr01 INTO lv_dcpfm WHERE bname EQ syuname. As a comparison, the same conversion Do you know if and how that can be changed to show 2 decimals only? Includes special power management circuitry that enhances the peak power capability of the USB port by storing excess energy and then releasing it as needed. QUAN with the length 31 and 14 decimal places. The highest precision is achieved on databases that support For this we require the currency key and the amount that needs to be converted. This function module does not define any Exceptions. Specify the required direction for mapping, i.e. I think it is a good idea to post those topics as 'Ask a Question' in the 'Answers' section of the community. This is known as currency amount formatting. To conclude, currency amount formatting is a function that helps to display amounts with the correct number of decimal places according to the specification of an associated currency. The content of such an ABAP field is transferred into a string when the data is handed over to the internal data container of the SAP Gateway Foundation framework. Because the primary key field WAERS in currency code table TCURC is the SAP-specific coded representation of currencies. Optional (if the current data source is client-specific). You can incorporate the generated function modules into the source code of your BAPI as required. https://blogs.sap.com/2020/11/03/how-to-check-the-maximum-length-of-a-function-import-parameter-in-segw-based-odata-services. SD_CONVERT_CURRENCY_FORMAT is a standard SAP function module available within R/3 SAP systems depending on your version and release level. This will then be available for you and other users to easily find by simply searching on the object name SD_CONVERT_CURRENCY_FORMAT or its description. Optional (if the current data source is client-specific). The purpose of this page is to clarify the understanding of the function module CONVERT_TO_LOCAL_CURRENCY. I hope this information will be useful to you. The program DEMO_CDS_UNIT_CONVERSION accesses the view in a SELECT The result has the data type CURR with the same technical attributes as the actual parameter passed to amount. SD_CONVERT_CURRENCY- Hang on, isnt that a pure user interface topic? This would be one option. statement. currencies with decimal places between 0 and 5. The input fields for the name of the function module and the short text contain suggested values which you can accept or change. We also specify the SAP function module. It first derives the internal value in string format using function module CURRENCY_AMOUNT_IDOC_TO_SAP_L and then moves the string value into the correctly typed field using the built-in ABAP type conversions. which are optional), to which the actual parameters a1, a2, must be assigned when called using =>. The literals #cdsboolean.TRUE, These are the EXPORTING parameters of this function module. REPLACE ALL OCCURRENCES OF lc_dot IN lv_amount_1 WITH space. SD_CONTRACT_COPY_CONDITIONS- My question might be at the wrong place but you might be able to refer me to the right place. While debugging, I noticed that many people dont use the standard SAP_CONVERT_TO_CSV_FORMAT Function Module to export tables to a .csv file. We will then move on to discuss modeling aspects in OData version 2.0 and version 4.0, before digging deeper into the corresponding data handling in SAP Gateway Foundation. Below mentioned function module converts the data to two decimal before saving to table And the conversion to correct decimals for end-user viewing. type. Thanks for the code, not a bad idea despite the limitations already mentioned by Shai Sinai, However, the suggested link for Excel export. well, there's room for improvement, as noted in the comment section of that blog post , This looks great. Here's an example code to get started: In this example code, we first define the SAP connection parameters including the username, password, hostname, system number, and client number. Below is the pattern details for this FM showing its interface including any import and export parameters, exceptions etc as well as any documentation contributions (Comments) specific to the object. This characteristic can be set for function import parameters in the model provider class. CONVERT_AMOUNT_TO_CURRENCY is a standard SAP function module available within R/3 SAP systems depending on your version and release level. keyword parameters p1, p2, (some of In OData versions 2.0, the situation is a little more difficult. As a prerequisite for the example, the currencies and conversion rules must be available in the corresponding database tables. Exchange rate date for column GDATU of the DDIC database table TCURR.
