How to fix this error?

Check entries of CNVFIELDS for table &V1& in comparison with priority
routine defined for this table in CNVSTEPS with TIMESTEP = 'PC' to de
cide which of the fields should be marked with PRIORITY flag.
<ZH>Note: </>
Setting PRIORITY flag only makes sense if CNVTABLES-SUMUP is set to 'A'
(there are 2 ways to use priority duplicate handling:
CNVTABLES-SUMUP = 'P' for table &V1& or
CNVTABLES-SUMUP = 'A' and exactly one field marked with PRIORITY flag in
CNVFIELDS for table &V1&
).

• What is the cause and solution for SAP error message CNV_00001209 - Priority flag is set for more than one field of table &1. ?

  The SAP error message CNV_00001209 indicates that there is a conflict in the configuration of priority flags for fields in a specific table. This typically occurs during data migration or conversion processes, particularly when using SAP's Data Migration tools or the SAP S/4HANA Migration Cockpit.
  Cause:
  The error arises when more than one field in the specified table has been marked with a priority flag. In data migration scenarios, priority flags are used to determine which field's value should take precedence when there are conflicting data entries. If multiple fields are flagged as priority, the system cannot determine which one to prioritize, leading to this error.
  Solution:
  To resolve this error, you need to ensure that only one field in the specified table has the priority flag set. Here are the steps to do this:
  
  
  Identify the Table: Check the error message for the specific table name indicated by &1.
  
  
  Review Field Configuration: Access the configuration settings for the table in question. This may involve looking at the data mapping or transformation rules defined in your migration project.
  
  
  Adjust Priority Flags:
  
  Determine which field should be the priority field based on your business requirements.
  Remove the priority flag from all other fields in the table, ensuring that only one field retains the priority flag.
  
  
  
  Test the Changes: After making the adjustments, re-run the migration or conversion process to verify that the error has been resolved.
  
  
  Documentation: Document the changes made for future reference and to ensure that the configuration aligns with your data migration strategy.
