The annotations can also be set for OData version 2.0 services depending on your UI client technology. I have an issue with Function Import parameters length. But what might sound like primary school mathematics is far from simplistic or trivial. 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. Comparing OData versions 2.0 and 4.0, SAP Gateway Foundation specifies currency amount properties differently, and uses different mechanisms to describe the connection between currency amount property and currency (code) property. The result has the data type They get more attention there and experts find them easier. ENDIF. Contains the field names of the external BAPI structure. I hope this information will be useful to you. If "X" (default value), the decimal places of the result are moved as specified by the decimal places of the target currency (see below). QUAN with the length 31 and 14 decimal places. 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. A table is displayed containing suggestions for the conversion of each field of the external BAPI structure. Seems like that with Function Import it doesnt work. Now, currencies are often provided in units and sub-units, that is, the currency amounts allow for different numbers of decimals to the right of the decimal point. The reverse is also not possible. As a comparison, the same conversion 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 . The function module is stored in the Function Builder in the function group you specified. Possible currencies and their decimal places are based on the database tables TCUR of the package SFIB. From 7.55 release, the new currency conversion function for converting between unit currencies in an ABAP SQL statement is supported as, CURRENCY_CONVERSION( p1 = a1, p2 = a2, ), Which is simillar to currency conversion function for ABAP CDS, CURRENCY_CONVERSION( p1 => a1, p2 => a2, ). UNIT_CONVERSION( p1 => a1, p2 => a2, ) 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. :to_currency as currency } The program DEMO_CDS_CURRENCY_CONVERSION accesses the view in a SELECT statement. DECIMAL_SHIFT( p1 => a1, p2 => a2, ). For more information, choose F1 help for columns Status and Conv. In addition to the source text for the function module you can have a blank . With the ABAP RESTful Programming model and OData version 4.0 you just need to specify appropriate CDS annotations and the formatting works out of the box. In the field Function group, enter the name of the function group to which the generated function module is to be added. ***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. 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. Later versions of SAP Gateway Foundation allow for creation of OData services based on CDS (Core Data Services) through mapped data sources (MDS), referenced data source (RDS), or auto exposure. In a few cases it may be necessary to manually edit the source code of a function module that has been automatically generated. You may call method SET_FUNC_IMP_MAX_LEN_CHECK at the parameter (interface /IWBEP/IF_MGW_ODATA_PARAMETER) to set it to ABAP_TRUE or ABAP_FALSE. https://blogs.sap.com/2020/11/03/how-to-check-the-maximum-length-of-a-function-import-parameter-in-segw-based-odata-services. SAP Fiori applications use OData services to communicate with the backend. These are the IMPORTING parameters of this function module. thank you very much for this detailled explanation. This function module does not define any Exceptions. 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. Hence, Edm.Decimal is the natural primitive type to be used. The following CDS view calls a currency conversion in the SELECT list Use method SET_UNIT_PROPERTY at the property that represents the currency amount. I described it in some more detail in the following blog post. If you do not want to use structure binding, you need to explicitly specify the relationship in the model provider class. Andre Fischer : do you know someone who could have a quick look? To know more details on handling the currency conversions, its roles and limitations, please check the ABAP Keyword Documentation. These are the CHANGING parameters of this function module. At this point we can hang the converted file with the FM SAP_CONVERT_TO_CSV_FORMAT to lt_file. Conversion functions for converting between units and between currencies in a Released Date: The program DEMO_CDS_DECIMAL_SHIFT accesses the view in a SELECT Your UI client must be able to handle that. 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. I found my mistake however it's not working correctly, I took debug screenshots (attached) after 'append lv_header to lt_file'. Alerting is not available for unauthorized users. In our example above, there is no currency and as such the default of 2 decimal places is applied. which are optional), to which the actual parameters a1, a2, must be assigned when called using =>. 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. 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. SD_CONVERT_CURRENCY_FORMAT is a standard SAP function module available within R/3 SAP systems depending on your version and release level. value1;part2, value2 should be generated as "value1;part2";value2 (and not value1;part2;value2). Clients might need the information which property X contains the currency for a given property Y that holds an amount. 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. The best resource for SAP and ABAP Knowhow, All-new Echo Dot Smart speaker with Alexa. CONVERT_TO_LOCAL_CURRENCY translates a foreign currency amount into the desired local currency. SAP Business ByDesign, for example, stores currency amounts as decimal floating points (mainly dictionary type DF34_DEC). It does, and it has also been decided to include some of the formatting features in that layer. It will Display 1000 Yen by converting the amount based on TCURX values Add a Comment Alert Moderator No matter how the conversion is made, the same results cannot Or, would you consider 123.00 in any currency or only in those with 2 decimal places? a prerequisite for the example, the units and their conversion rules must be available in the corresponding database tables. For OData version 2.0, SAP services use a specific property attribute sap:unit at the amount property. 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. If the type of the actual parameter passed to amount has two decimal places, its value is set to the number of decimal places of the passed currency. 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. CONDENSE lv_amount_1 NOGAPS. The USB power cable eliminates the need to find an AC outlet near your TV by powering Amazon Fire TV directly from your TV's USB port. If you would program your model provider class, then the mechanisms will be quite similar. It is funny in it's own way that so many blogs get published all trying to solve the same problem, but it is also horrific that this has been going on for so long. The Function Module AIPB_CURRENCY_SAP_TO_EXTERNAL (Convert currency amount and code from SAP into external format) Table TCURC connects this SAP-specific code to the alphabetic ISO code. This is known as currency amount formatting. See here to view full function module documentation and code listing, simply by entering the name SD_CONVERT_CURRENCY_FORMAT into the relevant SAP transaction such as SE37 or SE80. 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 target currency must be passed as a parameter. This is equivalent to the built-in data type P (packed number). To regenerate an existing function module you must first manually delete the function module and then generate it afresh. I went a little bit further and got the exact length from the MPC complex structure (in my case named serialdetail) used in the Function Import. SD_CONVERT_CURRENCY_FORMAT- These exceptions are described in. statement. ENDIF.ENDFUNCTION. If you use other data types or other decimal settings, the determination will not work as expected. CALL FUNCTION 'CONVERT_AMOUNT_TO_CURRENCY' EXPORTING date = sy-datum foreign_currency = 'USD' foreign_amount = '2000.00' local_currency = 'EUR' IMPORTING local_amount = amount. Data Formats and Structures. Source currency from column WAERS of the DDIC database table TCURC. The information will be evaluated by the OData library implementation when the parameters are transferred to the Gateway framework implementation. The precision of the result of the unit conversion depends on the database platform. These rules can be edited using transaction OB08. is a literal that is cast to the required type. To generate the function modules, the relevant internal and external data formats must have been created in the ABAP Dictionary. The following CDS view entity performs a currency conversion in the SELECT list for the column AMOUNT of the DDIC database table DEMO_PRICES. But a primitive property for an amount does not make sense without reference to the currency. You may want to compare this to the example provided in the second blog post of the series. library which allows Python to interact with SAP systems through Remote Function Calls (RFCs). But with the OData version 4.0 stack the complex annotations are created automatically. CONVERT_AMOUNT_TO_CURRENCY I cannot provide one ad hoc. 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. ***Convert to SAP external format WRITE lv_internal TO lv_external CURRENCY lv_waers. The program DEMO_CDS_UNIT_CONVERSION accesses the view in a SELECT The result has the data type The source unit actual parameter passed to amount. Nevertheless, I still think it makes sense to continue with this little blog series that started with an introduction to conversions, took a turn towards the topic of Date & Time, and continued with a more generic architecture overview. The value passed is rounded to two decimal places before it is converted. Converting Between Int. (You can also define your own headings in a so-called "field catalog".) 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. We also rename and convert the date and time columns to pandas datetime format. It is not yet possible to use this transaction to regenerate an existing function module. SD_CONTRACT_CONDITION_TYPES-. The functions have 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). Built in Smart Home hub. To finalize the formatting process, the minus sign for negative values is re-positioned from the end of the string to the front. In the appropriate input fields, enter the names of the external BAPI structure and the internal working structure you are making the conversion between. The SAP Gateway Foundation framework offers a method to retrieve filter information as select options in GET_ENTITYSET methods of the data provider class. These are the IMPORTING parameters of this function module. REPLACE ALL OCCURRENCES OF lc_com IN lv_amount_1 WITH space. In OData services delivered by SAP, the maximum length of a currency code property is 5. the framework will use the ABAP dictionary information of the ABAP structure (database table VBAK in this case). statement. For OData version 4.0, SAP services use annotations. ***Fetch records from USR01 CLEAR: lv_dcpfm. Did I mix it up with currency conversion? *" The Curr field, which is the required format PARAMETER :w_tgt type BAPICURR-BAPICURR. 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. The output that we get is in the required format. 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. As a comparison, the same conversion is also performed using the function module CONVERT_TO_LOCAL_CURRENCY. CONVERT_CURRENCY function is an SQL representation of the SQLScript built-in function CE_CONVERSION, and internally uses CE_CONVERSION for computation. TRANSLATE lv_amount_1 USING lc_con. Specify the required direction for mapping, i.e. library using pip or conda before running the code. 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). and Ext. The Japanese Yen (JPY) has no sub-units and hence no decimal places shall be shown. All of that is business functionality deeply embedded into the logic of the different application components. statement. 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. SD_CONVERT_CURRENCY- 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. 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. Here, the target unit is passed to the parameter in question. It is more likely to get a quick answer. #cdsboolean.true, #cdsboolean.FALSE, and However, examining the code I found this comment within the FM SAP_CONVERT_TO_TEX_FORMAT (called within the FM SAP_CONVERT_TO_CSV_FORMAT): To overcome this obstacle, I have written a few lines of code (a draft), which I want to share with you, which allows you to obtain the header line and add it to the .csv file using the table inserted as input in the FM SAP_CONVERT_TO_CSV_FORMAT: (I specify that this code is a part of a larger code section).
