• What is the cause and solution for SAP error message CNV_00001246 - More than one priority routine defined for table &1 ?

  The SAP error message CNV_00001246 indicates that there is more than one priority routine defined for a specific table in the context of data migration or conversion processes, typically associated with the SAP S/4HANA migration or other data transformation projects.
  Cause:
  This error occurs when the system detects multiple priority routines for the same table. Priority routines are used to determine the order in which data is processed during migration. Having more than one routine can lead to ambiguity in processing, as the system does not know which routine to prioritize.
  Solution:
  To resolve this error, you need to ensure that there is only one priority routine defined for the specified table. Here are the steps you can take:
  
  
  Identify the Table: Check the error message for the specific table name indicated by &1.
  
  
  Review the Routines: Access the relevant configuration or migration settings in your SAP system to review the defined routines for the identified table.
  
  
  Consolidate Routines: If you find multiple priority routines, you will need to consolidate them into a single routine. This may involve:
  
  Merging the logic of the routines if they are intended to perform similar tasks.
  Deciding which routine should be kept based on business requirements.
  
  
  
  Adjust Configuration: After consolidating the routines, adjust the configuration in the SAP system to ensure that only the selected priority routine is active for the table.
  
  
  Test the Changes: After making the necessary adjustments, run the migration or conversion process again to ensure that the error is resolved.
