How To Fix CNV_20310_CHECK028 - Duplicate priority provided for target CC &1 target controlling area &2

CNV_20310_CHECK028 - Overview

• Message type: E = Error

• Message class: CNV_20310_CHECK -

• Message number: 028

• Message text: Duplicate priority provided for target CC &1 target controlling area &2

What causes this issue?

Multiple priority indicators specified for the target cost center &V1&
in controlling area &V2&. This can lead to inconsistencies during the
conversion.
To run the transformation solution each target cost center must have
exactly one source cost center with the priority indicator set
(reference cost center) or exactly one source cost center from the
reference controlling area in case the solution Controlling Area Merge
is used.
If the solution Controlling Area Merge is used, and no priority is
provided for a target cost center, the priority indicator is taken from
the controlling area mapping. This is only possible if exactly one of
the source cost centers is in the reference controlling area. If two or
more of the source cost centers are in the reference controlling area
multiple priority indicators are provided. If none of the source cost
centers is in the reference controlling area no priority indicator is
provided.
You cannot run the transformation solution because certain prerequisites
have not been met. Please change your mapping accordingly.

CNV_20310_CHECK028 - Details

• The SAP error message CNV_20310_CHECK028 indicates that there is a duplicate priority assigned to a target cost center (CC) in a specific target controlling area. This error typically arises during data migration or conversion processes, particularly when using SAP's Conversion Tools or during the implementation of SAP S/4HANA.
  
  Cause:
  The error occurs when:
  
  Two or more cost centers in the target controlling area have been assigned the same priority. In SAP, priorities are used to determine the order in which cost centers are processed or migrated.
  The data being imported or converted has not been properly validated, leading to conflicts in priority assignments.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Duplicate Priorities:
  
  Review the data being imported or converted to identify which cost centers are assigned the same priority in the target controlling area.
  You can do this by checking the mapping or transformation rules used in the migration process.
  
  
  
  Adjust Priorities:
  
  Modify the priorities of the
