CNV_20600_CHECK058 - Implicit merges due to mapping of company codes

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20600_CHECK - Messages for Check classes

• Message number: 058

• Message text: Implicit merges due to mapping of company codes

What causes this issue?

There are <DS:TX.CNV_MBT_IMPLICIT_MERGE>implicit merges</> due to the
mapping of the company codes.
If according to the mapping a company code is converted to a company
code that already exists, these two company codes are merged. If the
existing company code is not included in the mapping, this is an
<DS:TX.CNV_MBT_IMPLICIT_MERGE>implicit merge</>, that is, a merge that
is not defined directly (explicitly) in the mapping, but follows
implicitly from the mapping and the existing company code.
Example: Company code A is renamed into B (mapping: A -> B). However
company code B exists already and is not meant to be changed into
another company code. This would amount to an implicit merge of A and B.
For these <DS:TX.CNV_MBT_IMPLICIT_MERGE>implicit merges</>, the same
checks as for explicit merges are required (mapping: A -> B; B -> B).
We require that all company codes are included in the mapping, which are
part of an identified <DS:TX.CNV_MBT_IMPLICIT_MERGE>implicit merge</>.

System Response

Error

How to fix this error?

are target values and already exist before the conversion.

• What is the cause and solution for SAP error message CNV_20600_CHECK058 - Implicit merges due to mapping of company codes ?

  The SAP error message CNV_20600_CHECK058 typically occurs during data migration processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there are implicit merges happening due to the mapping of company codes, which can lead to data inconsistencies or conflicts.
  Cause:
  The error is generally caused by the following scenarios:
  
  
  Company Code Mapping Conflicts: When multiple source company codes are mapped to a single target company code, it can lead to implicit merges. This means that data from different source company codes will be combined into one, which may not be the intended outcome.
  
  
  Data Overlap: If the same data (e.g., customer or vendor records) exists in multiple source company codes and is being mapped to a single target company code, it can create conflicts.
  
  
  Inconsistent Data Structures: Differences in the data structure or configuration between the source and target systems can also lead to this error.
  
  
  Solution:
  To resolve the CNV_20600_CHECK058 error, consider the following steps:
  
  
  Review Company Code Mapping: Check the mapping of company codes in your migration settings. Ensure that each source company code is mapped correctly and that there are no unintended overlaps.
  
  
  Adjust Mapping: If multiple source company codes need to be merged, ensure that the data is consistent and that you have a clear strategy for handling duplicates. You may need to create additional target company codes if necessary.
  
  
  Data Cleansing: Before migration, clean the data in the source system to eliminate duplicates and ensure that the data is consistent across company codes.
  
  
  Test Migration: Perform a test migration with a subset of data to identify any potential issues before executing the full migration.
  
  
  Consult Documentation: Refer to SAP's official documentation or notes related to the specific migration tool you are using for additional guidance on handling company code mappings.
  
  
  Seek Expert Help: If the issue persists, consider consulting with an SAP expert or a consultant who specializes in data migration to assist in resolving the issue.
