How To Fix CNV_20211_CHECK054 - Implicit merges due to mapping of companies

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20211_CHECK - Messages for check functions (company conversion)

• Message number: 054

• Message text: Implicit merges due to mapping of companies

What causes this issue?

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

How to fix this error?

You must also add companies as source values to the mapping if they are
target values, and already exist before the conversion.

• What is the cause and solution for SAP error message CNV_20211_CHECK054 - Implicit merges due to mapping of companies ?

  The SAP error message CNV_20211_CHECK054 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 companies, which can lead to data inconsistencies or conflicts.
  Cause:
  The error is generally caused by the following factors:
  
  
  Company Code Mapping Issues: The mapping of company codes in the migration process may not be set up correctly. If multiple source company codes are mapped to a single target company code, it can lead to implicit merges.
  
  
  Data Overlap: If there are overlapping data entries for the same entities (e.g., customers, vendors) across different company codes, the system may attempt to merge these entries implicitly, which can cause conflicts.
  
  
  Configuration Errors: Incorrect configuration in the migration settings or in the source system can lead to this error.
  
  
  Solution:
  To resolve the CNV_20211_CHECK054 error, you can take 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 to the appropriate target company code without overlaps.
  
  
  
  Data Cleansing:
  
  Perform data cleansing in the source system to eliminate any duplicate or conflicting entries that may cause implicit merges. Ensure that the data is consistent and does not overlap across different company codes.
  
  
  
  Adjust Migration Settings:
  
  If necessary, adjust the migration settings to prevent implicit merges. This may involve changing how data is mapped or processed during the migration.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation related to the specific migration tool you are using. There may be specific guidelines or best practices for handling company code mappings.
  
  
  
  Testing:
  
  Conduct thorough testing of the migration process in a non-production environment to identify and resolve any issues before executing the migration in the live system.
