• Message class: CNV_20310_CHECK -

• Message number: 031

• Message text: Mapping values for controlling areas do not result in priority conflicts

What causes this issue?

The mapping values for controlling areas do not specify a merge. This
means that there will be no priority conflicts due to an
<DS:TX.CNV_MBT_IMPLICIT_MERGE>implicit merge</>.
An implicit merge could result in a priority conflict if cost centers in
controlling areas that are to be merged have the same name, and none of
the cost centers are in the reference controlling area.

This error typically arises in the context of SAP's data migration tools, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.
  
  Cause:
  The error occurs when the mapping of controlling area values leads to priority conflicts. This can happen if:
  
  Multiple source values are mapped to the same target value without a clear priority.
  The mapping rules defined for controlling areas are ambiguous or overlapping, leading to confusion about which source value should take precedence.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Review Mapping Configuration:
  
  Check the mapping configuration for controlling areas in your migration project.
  Ensure that each source value is mapped to a unique target value without overlaps.
  
  
  
  Define Clear Priorities:
  
  If multiple source values must map to the same target value, define clear priorities for these mappings.
