• What is the cause and solution for SAP error message CNV_DMC_MC_EXCEPTION162 - Only Paramters with type BAPIRET2 or FS4MIG_S_BAPIRET2 are valid ?

  The SAP error message CNV_DMC_MC_EXCEPTION162 indicates that there is an issue with the parameters being passed to a function module or BAPI (Business Application Programming Interface) in the context of a data migration or conversion process. Specifically, it states that only parameters of type BAPIRET2 or FS4MIG_S_BAPIRET2 are valid for the operation being performed.
  Cause:
  
  Incorrect Parameter Type: The function module or BAPI you are trying to call expects parameters of a specific type (either BAPIRET2 or FS4MIG_S_BAPIRET2), but the parameters being passed do not match these types.
  Data Migration Cockpit (DMC) Issues: This error is often encountered in the context of the SAP Data Migration Cockpit, where the data structure or mapping may not be correctly defined.
  Custom Code or Enhancements: If there are custom enhancements or modifications in the code that interacts with the BAPI, it may lead to passing incorrect parameter types.
  
  Solution:
  
  Check Parameter Types: Review the parameters being passed to the BAPI or function module. Ensure that they are of the correct type (BAPIRET2 or FS4MIG_S_BAPIRET2).
  Review Data Mapping: If you are using the Data Migration Cockpit, check the data mapping and transformation rules to ensure that they are correctly defined and that the expected parameter types are being used.
  Debugging: If you have access to the ABAP code, you can debug the function call to see what parameters are being passed and identify where the mismatch occurs.
  Consult Documentation: Refer to the SAP documentation for the specific BAPI or function module you are using to understand the expected parameter types and structures.
  SAP Notes: Check for any relevant SAP Notes that may address this issue or provide additional guidance.
