Calling RFC BAPI within SAP Data Services

Published By : Satish Boda, SAP Global Delivery | SAP Consulting.

Technology: SAP Data Services, SAP Bank Analyzer.

Below are the End-to-End steps for writing legacy “Financial Transaction” data to SAP Bank Analyzer by calling RFC BAPI “FIN_TRANS_MODIFY”.

Establish connectivity :-

Install R/3 functions on SAP BANK ANALYZER Web Application Server (WAS).

Establish RFC connectivity between SAP BANK ANALYZER and SAP DATA SERVICES.

Build SAP Data Services Job :-

Login to the SAP Bank Analyzer system. Launch “BAPI Explorer” via T-code “BAPI” in SAP Bank Analyzer.

Create DATASTORE of type “SAP Applications” by entering the parameters of BANK ANALYZER system.

Import BAPI metadata in SAP DATA SERVICES.

The BAPI metadata looks like below with input and output parameters.

The input parameters are of 2 types : Scalar & Table parameters.

Create a nested NRDM structure for the source data similar to BAPI Input structure.

Make a “new function call” to call the BAPI.

Map the input columns to the BAPI scalar parameters using the wizard. Take the help of scrolling option.

Map the input schema to the BAPI Table parameters as below.

Prerequisite:-

  • Ø The column names of the input schema should match to the names of the BAPI input table. The input columns are mapped automatically to the BAPI table columns by matching column names.
  • Ø The input data type of columns should to be similar to the column data type of BAPI.

Select the RETURN table as output schema.

After hitting finish, the query appears as below.

Un-nest the RETURN table to write the details to a database table.

Run the Job :-

The RETURN table captures the messages returned by BAPI. This data can be analyzed to find successful entries.

  • Nice write up, I however have a problem with the output table. I get a”Unknown SAP Output Data error” which appears to happen when there are too many output parameters. I can not change the function to reduce the number of parameters so do you have any other solution.

  • Nice write up! When you create your nested structure, do you do any joins?

    “Create a nested NRDM structure for the source data similar to BAPI Input structure.

    Currently I’m calling material creation bapi which has header and then tables. And my tables appear to be including data for every material. How do I ensure the bapi call includes only one item at a time?

  • Adding details steps for calling BAPI in bods :-

    Steps to call BAPI into BODS

    1 – Import BAPI (BAPI_CUSTOMER_HIERARCHIE_INS)  into SAP datastore – Function – Import by name .

    2 – Open the BAPI by right click and open .

    3 – Copy Node (Table) by right click and copy :-

    4 – Add query transform into dataflow and double click it and right click on output schema and paste it  :-

    5 – Complete the mapping by making Node as Current (Right click and select Make Current) :-

    6 – Right click and Make current to Query and apply where clause as Gen_row_num=1 to populate duplicate records into target (Gen_Row_Num function must be use into previous qry transform of calling BAPI) :-

    7 – From clause should be checked for all nodes  (This is mandatory else bods will give error) :-

    8 – Call BAPI into query by right click and selecting “New Function call” :-

    9 – Map all input required parameters and select on Next and select Return parameter as target and RFC_Retcode.

    10 – Add new qry transform and drag RFC_Retcode and Nodelist as return parameter .

    11 – If return parameter is in format of Table (nodes) then right click and select on Unnest  (It is mandatory else bods will give error) :-

    12 – Add target table and validate the job and execute it .
