  I4687 Program (&1), subroutine (&2): Return value &3
  Cause:
  This message typically arises when a subroutine in an ABAP program returns a value that does not match the expected return type or value. This can happen due to various reasons, such as:
  
  Incorrect Return Value: The subroutine is designed to return a specific type of value, but it returns a different type or an unexpected value.
  Logic Errors: There may be logical errors in the code that lead to incorrect values being returned.
  Data Type Mismatch: The data type of the return value may not match the expected data type defined in the subroutine signature.

  Solution:
  To resolve this error, you can take the following steps:
  
  Check Subroutine Logic: Review the logic within the subroutine to ensure that it is correctly calculating or determining the return value.
  Verify Return Type: Ensure that the return value matches the expected data type defined in the subroutine. If the subroutine is expected to return an integer, for example, make sure it does not return a string or any other type.
  Initialize Variables: Make sure that all variables used to compute the return value are properly initialized before they are used.
  Debugging: Use debugging tools in SAP to step through the code and observe the values being returned. This can help identify where the logic may be going wrong.
  Check Documentation: If the subroutine is part of a standard SAP program or function module, refer to the SAP documentation to understand the expected behavior and return values.
