• What is the cause and solution for SAP error message I4729 - Return value (&) is not defined ?

  The SAP error message I4729, which states "Return value (&) is not defined," typically occurs in the context of ABAP programming or when working with function modules, BAPIs, or RFC calls. This error indicates that a return value being processed is not recognized or defined in the system.
  Cause:
  
  Undefined Return Value: The return value being passed back from a function module or method is not defined in the corresponding structure or table.
  Incorrect Function Module Call: The function module or method being called may not be set up correctly, leading to unexpected return values.
  Data Type Mismatch: There may be a mismatch between the expected data type of the return value and what is actually being returned.

  Check Function Module/Method Definition: Verify the definition of the function module or method being called. Ensure that all expected return values are correctly defined in the interface.
  Review Calling Code: Inspect the ABAP code that calls the function module or method. Ensure that it is correctly handling the return values and that the expected return value is being processed.
  Debugging: Use the ABAP debugger to step through the code and identify where the return value is being set. This can help pinpoint the source of the issue.

  Consult Documentation: Review the SAP documentation for the specific function module or BAPI to ensure that you are using it correctly and that you understand the expected return values.
