The input fields for the name of the function module and the short text contain suggested values which you can accept or change. 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 formatting is executed at runtime when the SAP Gateway Foundation framework transfers the data between the data container used in the data provider class and the framework-internal data container. Next, we establish the SAP connection using, and call the function module with the selection parameters to extract the sales data. This is equivalent to the built-in data type P (packed number). If the value "X" or "TRUE" is passed to the parameter. Built in Smart Home hub. 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. The table below shows the actual parameters p1, p2, and their meaning. Or, would you consider 123.00 in any currency or only in those with 2 decimal places? FUNCTION z_currency_conversion . Possible currencies and their decimal places are based on the database tables TCUR of the package SFIB. We also rename and convert the date and time columns to pandas datetime format. #cdsboolean.false can also be specified for the input parameters The determination of the reference currency property works with structure binding only because reference fields information is tied to ABAP structures. The result has the data type They are not connected at that point in time but reference ABAP field names NETWR and WAERK. As a prerequisite for the example, the currencies and conversion rules must be available in . So, when my next blog is done (it is about CL_SALV_TABLE and editability BTW another recurring theme) and published then it will be time to see if I cannot be like King Canute and turn back the "Download Internal table from ABAP" tide of blogs. 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. I was just challenging this since we actually delegate this control/check to the GW Framework for typical EntitySets. Neither will it determine reference field information. Please help keep this info upto date and use the comments section below to add useful hints, tips and information specific to this SAP function. CLEAR: lv_length. 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. 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. 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. I found my mistake however it's not working correctly, I took debug screenshots (attached) after 'append lv_header to lt_file'. ENDIF.ENDFUNCTION. within the package AIR. But a primitive property for an amount does not make sense without reference to the currency. In the field Function group, enter the name of the function group to which the generated function module is to be added. We have learned that we do require different numbers of decimal places depending on the currency. CONVERT_CURRENCY function is an SQL representation of the SQLScript built-in function CE_CONVERSION, and internally uses CE_CONVERSION for computation. Next, we establish the SAP connection using pyrfc.Connection and call the function module with the selection parameters to extract the sales data. But how does the framework behave during OData request execution? If "FAIL_ON_ERROR" (default value), an error raises an exception; if "SET_TO_NULL", the result is reset to the, Source currency from column WAERS of database table, Target currency from column WAERS of database table, Exchange rate date for column WAERS of database table, Exchange rate type from column KURST of database table, Client whose rules are used to perform the currency conversion. SD_CONVERT_CURRENCY_FORMAT is a function module in SAP Logistics Execution application with the description Konvertierung von W. Table of Contents SD_CONVERT_CURRENCY_FORMAT : SAP Documentation, Help/Wiki pages, and Q&A Related Tables for SD_CONVERT_CURRENCY_FORMAT Related FMs for SD_CONVERT_CURRENCY_FORMAT 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). Associated Function Group: As a prerequisite for the example, the currencies and conversion rules must be available in the corresponding DDIC database tables. The ABAP code below is a full code listing to execute function module SD_CONVERT_CURRENCY_FORMAT including all data declarations. The decimal places of the source value are moved as specified by the decimal places of the source currency (see below). using the function module CONVERT_TO_LOCAL_CURRENCY. type. It does, and it has also been decided to include some of the formatting features in that layer. These are the CHANGING parameters of this function module. Please, To connect to SAP and get sales data using Python, we can use the. 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. In the event of an error, for example when a currency is not available, an exception is raised. It just checks whether the string contains a valid value and inserts the formatted result into the XML/JSON http response. 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). In the URI, currency amounts may appear as filter values. Exchange rate date for column GDATU of the DDIC database table TCURR. 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. V56O The target currency is passed here. The best resource for SAP and ABAP Knowhow. Convert between internal and external data structures. which are optional), to which the actual parameters a1, a2, must be assigned when called using =>. Existence of an installed Excel program on the PC or app server is not required. You also need to consider that table TCURC may contain entries that do not correspond to ISO currencies and may specify any number of decimal places, for example, USDN with 5 decimal places. Different processes need to observe different update frequencies. CURRENCY_CONVERSION( p1 => a1, p2 => a2, ) But where does the currency code come from? Do you mean the possibility of switching the max. with the domain prefix CDSBOOLEAN (case-sensitive) or the literals You may also need to install the. #cdsboolean.true, #cdsboolean.FALSE, and CDS view. Because the primary key field WAERS in currency code table TCURC is the SAP-specific coded representation of currencies. And you would then simply through an error message as the SAP Gateway framework does it using the new model feature which is by the way called USE_STRICT_FUNCTION_PARAM_CHK and not USE_STRICT_FUNCTION_PARAMETER_CHECK. 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). You may want to compare this to the example provided in the second blog post of the series. Is it just a parameter of /iwbep/if_mgw_appl_srv_runtime~execute_action? Add the Hue Hub for whole-home smart lighting (up to 50 light points) and bonus features. 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. The function CURRENCY_CONVERSION performs a currency conversion for the value passed to the formal parameter amount. Specifying a scale of 2 would support most currencies, such as EUR or USD, but would not fit to JPY and TND (see above). QUAN with the length 31 and 14 decimal places. The value passed is rounded to two decimal places before it is converted. We then define the selection parameters such as the date range for sales data. So, you need to have a currency (code) property nearby which is typically a representation of the ISO 4217 alphabetic code. Its internal data type CUKY has length 5. This bundle includes Echo Dot (3rd Gen) Charcoal and Philips Hue White A19 Medium Lumen Smart Bulb, 1100 Lumens. Admin; CA-DMS; In our example above, there is no currency and as such the default of 2 decimal places is applied. The first lines of code in the metadata provider class would create the two properties in the entity type the currency amount and the currency. If the function module is being used to convert currency amounts, the fixed point arithmetic for the selected function group must be switched on. I can tell you that I noticed an error: I wrote the code in Italian and then translated it. Would you interpret all amounts in JPY? It will Display 1000 Yen by converting the amount based on TCURX values Add a Comment Alert Moderator The source unit SAP Fiori applications use OData services to communicate with the backend. Subscribe for free to receive new posts and support my work. For other SAP HANA databases, replicate the . But you can easily translate the statements and examples to quantities, for example. With currency USDN (see example above), you would obtain a result with 5 decimals places, even though this contradicts the service metadata. DESCRIBE FIELD lv_amount_1 LENGTH lv_length IN CHARACTER MODE. As you will see in the links I have been challenged to try and fight this by writing a series of blogs myself about ABAP2XLSX, as clearly even after ten years no-one has heard of it. See you in the next post. 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. Nevertheless, the sap:semantics attribute will be there it is purely derived from the data type of the field in the ABAP structure and not regarded as conversion-related. 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. Like the reference fields in the ABAP dictionary, CDS views provide annotations to express if a field contains a currency code and to which currency code field an amount relates to: Again, the SAP Gateway Foundation framework evaluates this information to create appropriate service metadata. 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. Optional (if the current data source is client-specific). for the column AMOUNT of the database table DEMO_PRICES. Not all combinations of amounts and currency codes make sense in a filter query option.

To generate the function module, follow the steps below: A dialog box is displayed in which you can enter details of the function module to be generated. 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. please ping me when you have published your blog post so I can refer to it. We also specify the SAP function module. FUNCTION z_currency_conversion . The decimal places of the result are moved as specified by the decimal placesof the target currency (see below). I would just like the second the motion that you look into ABAP2XLSX. 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. 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. 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). This is either done by the chosen rate or through table TCURR. For this we require the currency key and the amount that needs to be converted. Before the conversion, the value passed is multiplied by 10 to the power of the number of decimal places of the source currency. The Function Module AIPB_CURRENCY_SAP_TO_EXTERNAL (Convert currency amount and code from SAP into external format) https://blogs.sap.com/2020/11/03/how-to-check-the-maximum-length-of-a-function-import-parameter-in-segw-based-odata-services. and Ext. Alerting is not available for unauthorized users, * REFERENCE(LV_EXTERNAL) TYPE CHAR30. If it does not work as just described, ensure that you check the data type used in the backend, the reference field information in the ABAP dictionary, and the structure binding or the unit property setting in your metadata provider class. Source currency from column WAERS of the DDIC database table TCURC. CONVERT_AMOUNT_TO_CURRENCY The result has the data type CURR with the same technical attributes as the actual parameter passed to amount. Client whose rules are used to perform the currency conversion. library which allows Python to interact with SAP systems through Remote Function Calls (RFCs). | DECIMAL_SHIFT( p1 => a1, p2 => a2, ) 1. The conversion is performed on the database, which means that part of the calculation takes place The conversion is performed on the database, which means that part of the calculation takes place using different rounding rules from ABAP. The value of that attribute denotes the name of the currency (code) property that must be part of the same entity type. 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. It is however part of the conversion functions provided by SAP Gateway Foundation to ease UI client development and to efficiently and consistently access the currency specifications in the backend. In the past, SAPGUI as a user interface technology had similar formatting requirements. a prerequisite for the example, the units and their conversion rules must be available in the corresponding database tables. 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 Optional (if the current data source is client-specific). For this we require the currency key and the amount that needs to be converted. The annotations can also be set for OData version 2.0 services depending on your UI client technology. A primitive property of type Edm.String with a maximum length of 3 would be suitable. The Japanese Yen (JPY) has no sub-units and hence no decimal places shall be shown. Check the correct usage of the iv_bind_conversions parameter and check if you did not switch off conversions on other levels of the service metadata (refer to this blog post). In OData services delivered by SAP, the maximum length of a currency code property is 5. lv_amount_2 = lv_amount_1. value1;part2, value2 should be generated as "value1;part2";value2 (and not value1;part2;value2).

These exceptions are described in. e.g. To know more details on handling the currency conversions, its roles and limitations, please check the ABAP Keyword Documentation. Did I miss something ? Below mentioned function module converts the data to two decimal before saving to table And the conversion to correct decimals for end-user viewing. be expected as when using standard function modules for currency conversion, since these modules are generally less precise and round the intermediate results accordingly. As a comparison, the same conversion is also performed using the function module CONVERT_TO_LOCAL_CURRENCY. I will not go into details about OData version 4.0. Now, we know something about the service model. Seems like that with Function Import it doesnt work. In essence for the last ten years there has been one blog very month (two this month) on the SCN about downloading ABAP internal tables into a file that can be read by Excel. Lets look at one version: select options. 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. The literals #cdsboolean.TRUE, The precision of the result of the unit conversion depends on the database platform. In addition to the source text for the function module you can have a blank FORM routine added for your own program code if you have to make manual modifications. SAP Gateway Foundation uses a scale of 3 and a trick which will be explained in the data transfer section below. SAP Business ByDesign, for example, stores currency amounts as decimal floating points (mainly dictionary type DF34_DEC). The target currency is passed as a host variable. To finalize the formatting process, the minus sign for negative values is re-positioned from the end of the string to the front. SD_CONVERT_CURRENCY_FORMAT is a standard SAP function module available within R/3 SAP systems depending on your version and release level. Please observe the parameter iv_bind_conversions in the last method call. The OData standard does not provide a specific primitive type for properties that represent currency amounts. I cannot provide one ad hoc. Processing type: Normal fucntion module. https://blogs.sap.com/2010/07/12/abap2xlsx-generate-your-professional-excel-spreadsheet-from-abap/. UNIT_CONVERSION( p1 => a1, p2 => a2, ) | CURRENCY_CONVERSION( p1 => a1, p2 => a2, ) To regenerate an existing function module you must first manually delete the function module and then generate it afresh. In the event of an error, for example when a currency does not exist, the result is reset to zero. 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. At this point in time, the formatting is done using function module CURRENCY_AMOUNT_SAP_TO_IDOC. For more information, choose F1 help for columns Status and Conv.

Hence, Edm.Decimal is the natural primitive type to be used. There are different types of exchange rates and different notations. If the parameter is not set, the system will not determine conversion-related information from the ABAP dictionary (refer to the first blog post of the series). ENDIF. Example: For VBAK-NETWR the currency information from VBAK-WAERK is used. ***Convert to SAP external format WRITE lv_internal TO lv_external CURRENCY lv_waers. 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. Did I mix it up with currency conversion? The value passed is rounded to two decimal places before it is converted. A currency would be considered with the following filter expression: $filter=TotalNetAmount gt 123 and TransactionCurrency eq JPY. and is part of the function group AIPB 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. At this point in time, the formatting is done using function module CURRENCY_AMOUNT_SAP_TO_IDOC. No matter how the conversion is made, the same results cannot Pay attention that neither FM SAP_CONVERT_TO_CSV_FORMAT nor your code (which simply adds the field separator, ";" in your case, after each field) are a complete/correct implementation of CSV file (according to the RFC) because they don't handle more complex like escape character or quotes. TRANSLATE lv_amount_1 USING lc_con. Table TCURC connects this SAP-specific code to the alphabetic ISO code.
