• What is the cause and solution for SAP error message SRFAC_IMPL028 - Only one returning parameter allowed ?

  The SAP error message SRFAC_IMPL028: Only one returning parameter allowed typically occurs in the context of SAP Business Workflow or when working with function modules or methods in ABAP (Advanced Business Application Programming). This error indicates that a function module or method is defined to return only one parameter, but the implementation is attempting to return more than one.
  Cause:
  
  Multiple Return Parameters: The function module or method is defined with a single returning parameter, but the implementation is trying to return multiple values.
  Incorrect Function Module Signature: The signature of the function module or method does not match the expected definition, leading to confusion about the number of return parameters.
  Misconfiguration in Workflow: If this error arises in a workflow context, it may be due to a misconfiguration in the workflow definition where multiple outputs are expected.
  
  Solution:
  
  
  Check Function Module/Method Definition: Review the definition of the function module or method to ensure that it is designed to return only one parameter. If you need to return multiple values, consider using a structure or table as the returning parameter.
  
  
  Modify Implementation: If you are implementing a function module or method, ensure that you are only returning one value. If you need to return multiple values, you can:
  
  Use a structure that contains multiple fields.
  Use a table to return multiple rows of data.
  
  
  
  Adjust Workflow Configuration: If the error occurs in a workflow, check the workflow configuration to ensure that it aligns with the expected parameters of the function module or method being called.
  
  
  Testing: After making the necessary changes, test the function/module or workflow to ensure that the error is resolved.
  
  
  Related Information:
  
  ABAP Documentation: Review the SAP documentation for function modules and methods to understand how to properly define and implement return parameters.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other developers who may have encountered similar issues.
  Debugging: Use the ABAP debugger to step through the code and identify where the multiple return parameters are being defined or returned.
  
  By following these steps, you should be able to resolve the SRFAC_IMPL028 error and ensure that your function module or method adheres to the expected return parameter structure.
