• What is the cause and solution for SAP error message CNV10300012 - Conversion routine &1 with &2 > 4 parameters will not be executed! ?

  The SAP error message CNV10300012 indicates that a conversion routine is being called with more than four parameters, which is not supported in the context of the operation being performed. This error typically arises during data migration or conversion processes, particularly when using SAP's Data Migration tools or the SAP S/4HANA Migration Cockpit.
  Cause:
  The primary cause of this error is that the conversion routine defined in the migration process is attempting to pass more than four parameters. In SAP, certain function modules or conversion routines have limitations on the number of parameters they can accept, and exceeding this limit results in the error message.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Conversion Routine: Check the specific conversion routine that is being called. You can find this in the migration or conversion settings. Ensure that it is designed to handle the number of parameters being passed.
  
  
  Modify the Routine: If you have access to the code of the conversion routine, consider modifying it to accept fewer parameters. This may involve combining some parameters into a single structure or changing the logic to reduce the number of parameters.
  
  
  Use Alternative Routines: If modifying the existing routine is not feasible, look for alternative conversion routines that can achieve the same result but are designed to handle the required number of parameters.
  
  
  Check Migration Settings: Review the settings in the migration cockpit or the data migration tool you are using. Ensure that the mappings and transformations are correctly set up and do not inadvertently pass extra parameters.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using. There may be specific guidelines or updates that address this issue.
  
  
  Contact SAP Support: If you are unable to resolve the issue on your own, consider reaching out to SAP support for assistance. They may provide insights or patches that can help resolve the error.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide updates to the conversion routines.
  SAP Community: Engage with the SAP Community forums where other users may have encountered and resolved similar issues.
  Testing: After making changes, thoroughly test the migration process to ensure that the conversion routines work as expected without errors.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
