  The SAP error message WRF_WSUBST044 indicates that there is an issue with the data being returned from a Business Add-In (BAdI) implementation related to the substitution of materials. This error typically arises when the data provided by the BAdI does not meet the expected format or criteria, leading to inconsistencies in the material substitution process.
  Cause:
  
  Incorrect Data Handling: The BAdI implementation may not be correctly handling the input data, leading to incorrect or unexpected output.
  Data Type Mismatch: The data types of the original material and unit may not match the expected types in the system.
  Logic Errors: There may be logical errors in the BAdI implementation that cause it to return invalid data.
  Configuration Issues: The configuration settings for material substitution may not be set up correctly, leading to conflicts with the BAdI implementation.

  Check Data Types: Verify that the data types for the original material and unit are correct and consistent with what the system expects.
  Debugging: Use debugging tools to trace the execution of the BAdI implementation and identify where the incorrect data is being generated.
  Consult Documentation: Review the SAP documentation for the specific BAdI to ensure that it is being implemented correctly and that all required parameters are being handled.
