• What is the cause and solution for SAP error message DDLS523 - Output parameters & could not be mapped onto database types ?

  The SAP error message DDLS523 indicates that there is an issue with the mapping of output parameters in a database procedure or function. This typically occurs when the data types defined in the ABAP Dictionary do not match the expected database types, leading to a failure in the execution of the procedure or function.
  Cause:
  
  Data Type Mismatch: The output parameters defined in the ABAP program or function module do not correspond correctly to the data types defined in the database.
  Unsupported Data Types: The database may not support certain data types that are being used in the output parameters.
  Changes in Database Structure: If there have been recent changes to the database structure (like changes in data types or the addition of new fields), the existing mappings may no longer be valid.
  Incorrect Function Module Definition: The function module or procedure may have been incorrectly defined, leading to mismatches in expected output.
  
  Solution:
  
  Check Data Types: Review the data types of the output parameters in the ABAP program and compare them with the corresponding database types. Ensure that they are compatible.
  Adjust Function Module/Procedure: If the function module or procedure is incorrectly defined, modify it to ensure that the output parameters match the expected database types.
  Update ABAP Dictionary: If there have been changes in the database structure, update the ABAP Dictionary to reflect these changes. This may involve regenerating the function module or procedure.
  Use Compatible Types: If you are using custom types or structures, ensure that they are compatible with the database types. You may need to convert or cast types appropriately.
  Check for Unsupported Types: If you are using types that are not supported by the database (like certain complex types), consider changing them to simpler, supported types.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE11 (Data Dictionary), SE37 (Function Module), or SE80 (Object Navigator) to check and modify the definitions.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. Sometimes, specific versions of SAP may have bugs that are documented in SAP Notes.
  Debugging: If the issue persists, consider debugging the function module or procedure to trace where the mapping fails.
  Documentation: Refer to the SAP documentation for guidelines on data types and their compatibility with the database.
