• What is the cause and solution for SAP error message CNV_00001603 - No suitable priority routine was found for table &1; choose manually ?

  The SAP error message CNV_00001603 indicates that the system could not find a suitable priority routine for a specific table during a data migration or conversion process. This typically occurs in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data transfer processes.
  Cause:
  
  Missing Priority Routine: The system does not have a predefined priority routine for the specified table (&1), which means it cannot automatically determine how to handle the data for that table during the migration.
  Custom Tables: If the table is a custom table or not part of the standard SAP data model, the system may not have a built-in routine for it.
  Configuration Issues: There may be configuration issues in the migration settings that prevent the system from identifying the appropriate routine.
  
  Solution:
  
  
  Manual Selection: As the error message suggests, you can manually choose a priority routine for the table in question. This typically involves:
  
  Accessing the migration tool or transaction where the error occurred.
  Locating the table that triggered the error.
  Manually selecting an appropriate routine from the available options.
  
  
  
  Define Custom Routines: If no suitable routine exists, you may need to define a custom priority routine for the table. This involves:
  
  Creating a custom program or routine that specifies how to handle the data for that table.
  Registering this routine in the migration tool so that it can be recognized during the migration process.
  
  
  
  Check Documentation: Review the SAP documentation related to the specific migration tool you are using. There may be guidelines or examples on how to handle tables without predefined routines.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on handling similar situations.
