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 following CDS view calls a unit conversion in the SELECT list for The result has the data type CURR with the same technical attributes as the actual parameter passed to amount. But with the OData version 4.0 stack the complex annotations are created automatically. If the function module is being used to convert currency amounts, the fixed point arithmetic for the selected function group must be switched on. Client whose rules are used to perform the currency conversion. Did I miss something ? Regarding the USE_STRICT_FUNCTION_PARAM_CHK feature, where will it be? with keyword parameters p1, p2, (some of which are optional), to which actual parameters a1, a2, must be assigned when a function is called. We convert the sales data into a pandas dataframe and filter out irrelevant columns such as material and plant. Currently, there are only two exceptions: CLF and UYW with a minor unit of 4. Since I last published a blog post on this topic, SAP Gateway Foundation has continued to evolve. for the column AMOUNT of the database table DEMO_PRICES in accordance with is the internal structure to be mapped onto the external structure or vice versa. As a prerequisite for the example, the currencies and their number of decimal places must be available in the corresponding database tables. REPLACE ALL OCCURRENCES OF lc_dot IN lv_amount_1 WITH space. The output that we get is in the required format. Its internal data type CUKY has length 5. This bundle contains Amazon Fire TV Stick Lite and Mission USB Power Cable. Rates might not be available for currency pairs, and so on. If "X" (default value), the decimal places of the result are moved as specified by the decimal places of the target currency (see below). In the field Function group, enter the name of the function group to which the generated function module is to be added. These are the CHANGING parameters of this function module. "ITAB1" cannot be converted to the row type of "LT_FILE". It just checks whether the string contains a valid value and inserts the formatted result into the XML/JSON http response. The following is an excerpt of the program DEMO_ASQL_CURRENCY_CONVERSION. Different processes need to observe different update frequencies. Hence, the reverse amount formatting cannot be executed either. . The result has the data type The target currency is passed as a host variable. The highest precision is achieved on databases that support This function module does not define any TABLE parameters. The following CDS view entity performs a currency conversion in the SELECT list for the column AMOUNT of the DDIC database table DEMO_PRICES. Using the same input, the output is similar as the above example. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. IF lv_internal IS NOT INITIAL. Nils Janen The colleagues suggested to post the question in the Fiori Elements Community: https://community.sap.com/topics/fiori-elements, Alerting is not available for unauthorized users, Right click and copy the link to share this comment, get_parameters has the value with 18 chars but the type is char(19), get_parameters_converted gets a value with 18 chars since it truncates at 18th position. We then define the selection parameters such as the date range for sales data. The FORM routine contains the same parameters as the generated function module. Released Date: decimal floating point numbers. Andre Fischer : do you know someone who could have a quick look? The function DECIMAL_SHIFT sets the decimal separator of the value that is passed to the formal parameter amount in accordance with a currency. All rights reserved. I will create a blog on this one for future colleagues. We will focus on currency amounts. However, I coudn't add the converted file itab1 to lt_file. Default: Content of the client column of the current row, Error handling. They are not connected at that point in time but reference ABAP field names NETWR and WAERK. CURR with the length 31 and 14 decimal places. I have an issue with Function Import parameters length. If set to ABAP_FALSE (default) the maximum length facet for Edm.String is not considered and input with greater length is accepted. the column DEC3 of the database table DEMO_EXPRESSIONS. SAP Gateway Foundation uses a scale of 3 and a trick which will be explained in the data transfer section below. The program DEMO_CDS_UNIT_CONVERSION accesses the view in a SELECT At this point in time, the select options just contain unconverted data. Next, we establish the SAP connection using, and call the function module with the selection parameters to extract the sales data. 2. In this blog post, we are going to take a deeper look at a very special conversion-related topic: the formatting of currency amounts. 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. If you use other data types or other decimal settings, the determination will not work as expected. Thanks. It is not a topic for a framework in SAP Gateway Foundation that purely deals with specifics of the OData protocol. As a comparison, the same conversion We also specify the SAP function module. 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. 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. must be passed as a parameter. 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). library which allows Python to interact with SAP systems through Remote Function Calls (RFCs). 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. It is not yet possible to use this transaction to regenerate an existing function module. 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. DECIMAL_SHIFT( p1 => a1, p2 => a2, ). This bundle includes Echo Dot (3rd Gen) Charcoal and Philips Hue White A19 Medium Lumen Smart Bulb, 1100 Lumens. To know more details on handling the currency conversions, its roles and limitations, please check the ABAP Keyword Documentation. I noticed the lv_testata. In the field Function group, enter the name of the function group to which the generated function module is to be added. Example: For VBAK-NETWR the currency information from VBAK-WAERK is used. These are the EXPORTING parameters of this function module. The table below shows the parameters p1, p2, and their meaning. Use method SET_UNIT_PROPERTY at the property that represents the currency amount. For this we require the currency key and the amount that needs to be converted. *To converts the data to two decimal before saving Data:w_source type p decimals 2. This function module does not define any Exceptions. In the event of an error, for example when a currency does not exist, the result is reset to zero. 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): This is equivalent to the built-in data type P (packed number). Built in Smart Home hub. In the event of an error, for example when a currency does not exist, the result is reset to zero. Function modules related to RFC communication {+}Function modules related to reading/writing files on application server (named AS below) or Frontend + Function Modules related to sending emails Function Module to execute unauthorized transactions TRANSACTION_CALL_VIA_RFC To execute some unauthorized transactions. Currency conversions are now possible in ABAP SQL as well as ABAP CDS. The value of that attribute denotes the name of the currency (code) property that must be part of the same entity type. As a prerequisite for the example, the currencies and conversion rules must be available in the corresponding database tables. 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). 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. round, decimal_shift, and decimal_shift_back Similarly, the framework evaluates reference field information in the dictionary and translates this into proper OData metadata. DESCRIBE FIELD lv_amount_1 LENGTH lv_length IN CHARACTER MODE. The table contains the following columns: Indicates if the conversion is possible or if data is missing. Based on the specific internal metadata settings, the ABAP OData Library can handle this string information in the context of the Edm.Decimal property. CLEAR: lv_length. 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 Function Module AIA_TOOL_CURRENCY_SAP_TO_EXTER (Convert currency amount and code from SAP into external format) As The Japanese Yen (JPY) has no sub-units and hence no decimal places shall be shown. Ex 5000000 should show up as 50,00,000. For OData version 2.0, SAP services use a specific property attribute sap:unit at the amount property. This is either done by the chosen rate or through table TCURR. The SAP Gateway Foundation framework offers a method to retrieve filter information as select options in GET_ENTITYSET methods of the data provider class. CDS view. SD_CONVERT_CURRENCY- Lets start by shedding some light on those questions. But where does the currency code come from? After the conversion, the result is divided by 10 to the power of the number of decimal places of the target currency. The target unit must be passed as a parameter. Alerting is not available for unauthorized users. within the package AIP. I found my mistake however it's not working correctly, I took debug screenshots (attached) after 'append lv_header to lt_file'. You may also need to install the. Converting Between Int. The function UNIT_CONVERSION performs a unit conversion for the value passed to the formal parameter quantity. 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). 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. All of that is business functionality deeply embedded into the logic of the different application components. 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. The reverse is also not possible. SAP NetWeaver AS ABAP Release 752, Copyright 2017 SAP AG. The target currency is passed here. 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. 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. using the function module CONVERT_TO_LOCAL_CURRENCY. Hence, your service will not show the relationship and the SAP Gateway Foundation framework will not use it for amount formatting. ELSEIF lv_dcpfm EQ lc_y. Add the Hue Hub for whole-home smart lighting (up to 50 light points) and bonus features. CONVERT_AMOUNT_TO_CURRENCY Associated Function Group: FUNCTION z_currency_conversion . These include the following: Conversion of currency amounts into the required external or internal format, Conversion of internal and external keys, for use for example by WBS elements (work breakdown structure). The program DEMO_CDS_CURRENCY_CONVERSION accesses the view in a SELECT You would expect that such a framework would support currency amounts. 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, ). I hope this information will be useful to you. Call transaction SE37 with function module CONVERT_TO_LOCAL_CURRENCY. and is part of the function group AIPB 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 functions have The function CURRENCY_CONVERSION performs a currency conversion for the value passed to the formal parameter amount. Please, To connect to SAP and get sales data using Python, we can use the. The following CDS view calls a currency conversion in the SELECT list The currency conversion is performed currencies with decimal places between 0 and 5. If you do not want to use structure binding, you need to explicitly specify the relationship in the model provider class. As a prerequisite for the example, the currencies and conversion rules must be available in the corresponding DDIC database tables. 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. 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. There are different types of exchange rates and different notations. It's free to sign up and bid on jobs. REPLACE ALL OCCURRENCES OF lc_com IN lv_amount_1 WITH space. These rules can be edited using transaction OB08. No additional Philips Hue hub required. Formatting? Convert between existing internal data structures and the BAPI data structures to be used in the interface. The function CURRENCY_CONVERSION performs a currency conversion for the value passed to the formal parameter amount. Thanks for reading Analytics musings by Karteek! SD_CONTRACT_CONDITION_TYPES-. They are not permitted as key properties of entity types. ***Convert to SAP external format WRITE lv_internal TO lv_external CURRENCY lv_waers. 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. Here is an example for an OData version 2.0 service. (sorry, it's been a while since I wrote in abap). SD_CONTRACT_READ_CONDITIONS- The framework updates the service metadata with the information required to control amount formatting. Internally, these literals are handled like the values "X" or " ". But you can easily translate the statements and examples to quantities, for example. 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_CONTRACT_COPY_CONDITIONS- Optional (if the current data source is client-specific). 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. In the SELECT list, the following CDS view sets the decimal separator statement. length check on and off? These are the IMPORTING parameters of this function module. If the function module is being used to convert currency amounts, the fixed point arithmetic for the selected function group must be switched on. 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. [1] P LENGTH 8 can store 2 * 8 1 (the sign) = 15 digits. is also performed using the function module UNIT_CONVERSION_SIMPLE. Because the primary key field WAERS in currency code table TCURC is the SAP-specific coded representation of currencies. In OData services delivered by SAP, the maximum length of a currency code property is 5. The facet scale that has been randomly selected for OData version 2.0 is not considered! *" The Curr field, which is the required format PARAMETER :w_tgt type BAPICURR-BAPICURR. 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. ***Constants CONSTANTS: lc_x TYPE xudcpfm VALUE X, lc_y TYPE xudcpfm VALUE Y, lc_dot TYPE c VALUE ., lc_com TYPE c VALUE ,, lc_con TYPE char2 VALUE ,.. ***Change the format IF lv_dcpfm EQ lc_x. A table is displayed containing suggestions for the conversion of each field of the external BAPI structure. Thanks, Nils. For more information, choose F1 help for columns Status and Conv. 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 is also performed using the function module CONVERT_TO_LOCAL_CURRENCY. If we apply structure binding. please ping me when you have published your blog post so I can refer to it. But you would need to manage all the currency definitions with their formatting-related properties within the UI client, while other parts of the currency definitions are required in the backend. 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. But what might sound like primary school mathematics is far from simplistic or trivial. I described it in some more detail in the following blog post.
