• Message number: 209

• Message text: Priority flag is set for more than one field of table &1.

What causes this issue?

"Priority" flag is set for more than one field of table &V1&. The value
of the field marked with the "Priority" flag will be written to a
special program variable of conversion program and can be used by the
priority routine to decide which of the entries that cause duplicates
should be written to the database. Therefore exactly one field should be
marked with the "Priority" flag.

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&
).

CNV_00001209 - Details

• 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.
