CNVA_20400_CHECK063 - Overview

• Message type: E = Error

• Message class: CNVA_20400_CHECK - Messages for contorlling areas checks

• Message number: 063

• Message text: A mix of explicit and implicit merges into a primary cost element

A mix of explicit and implicit merges into a primary cost element was
detected. This happens when cost elements will be merged, but the
mapping only contains a part of the source cost elements. The
transformation solution Controlling Area Merge does not support primary
cost elements. To change primary cost elements, a chart of accounts
conversion is required.

CNVA_20400_CHECK063 - Details

• The SAP error message CNVA_20400_CHECK063 indicates that there is a mix of explicit and implicit merges into a primary cost element during the migration or data transformation process. This typically occurs in the context of SAP S/4HANA migrations or when using the SAP Migration Cockpit.
  
  Cause:
  
  Explicit Merges: These are merges that are defined by the user, where specific cost elements are combined based on user-defined criteria.
  Implicit Merges: These are automatic merges that SAP performs based on predefined rules or settings in the system.
  The error arises when both types of merges are attempted on the same primary cost element, which leads to ambiguity in how the data should be processed.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Migration Data: Check the data that you are trying to migrate. Look for any cost elements that are being merged both explicitly and implicitly.
  
  
  Adjust Merge Settings: 
  
  If you have defined explicit merges,
