• What is the cause and solution for SAP error message S&537 - BAPI &1: BAPI function module &2 has no return parameter ?

  The SAP error message S&537 indicates that a BAPI (Business Application Programming Interface) function module is being called, but it does not have a return parameter defined. This can occur when the BAPI is expected to return a status or message, but the function module does not include a return structure.
  Cause:
  
  Missing Return Parameter: The BAPI function module you are trying to call does not have a return parameter defined. This is a requirement for BAPIs that are expected to provide feedback on the success or failure of the operation.
  Incorrect BAPI Usage: The BAPI might be used incorrectly in the calling program or function module, leading to the expectation of a return parameter that does not exist.
  Custom BAPI: If the BAPI is a custom implementation, the developer may have forgotten to include the return parameter.
  
  Solution:
  
  Check BAPI Definition: Verify the definition of the BAPI function module in transaction SE37 or SE80. Ensure that it has a return parameter defined. The return parameter is typically named RETURN and should be of type BAPIRET2.
  Modify BAPI: If you have access to modify the BAPI, you can add a return parameter to it. This involves:
  
  Opening the BAPI in SE37.
  Adding a new parameter of type BAPIRET2 to the function module.
  Implementing the logic to populate this return parameter with success or error messages.
  
  
  Review Calling Code: If you are calling the BAPI from another program or function module, ensure that you are not expecting a return parameter if the BAPI does not have one. Adjust the calling code accordingly.
  Consult Documentation: Check the SAP documentation or notes related to the specific BAPI you are using to understand its expected behavior and parameters.
  
  Related Information:
  
  BAPIRET2 Structure: This is a standard structure used in BAPIs to return messages. It typically contains fields like TYPE, ID, NUMBER, MESSAGE, and LOG_NO.
  SAP Notes: Search for relevant SAP Notes that might address issues with specific BAPIs or provide guidance on best practices for BAPI development.
  Testing BAPIs: Use transaction BAPI to test BAPIs directly and see their expected input and output parameters.
  
  By following these steps, you should be able to resolve the error and ensure that the BAPI functions as intended.
