SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20200_CHECK - Messages for check functions (company code merge)

• Message number: 053

• Message text: Temporary duplicates possible due to mapping of company codes &1 and &2

What causes this issue?

<DS:TX.CNV_MBT_TEMP_DUPLICATES>Temporary duplicates</> possible due to
mapping of the company codes &V1& and &V2&.
According to the mapping, you plan to convert company code &V1& into
&V2&. However, company code &V2& exists already and will be converted as
defined by the mapping to &V3&. In this case, temporary duplicates may
occur in the database if company code &V1& is converted at a point in
time when company code &V2& has not yet been converted. If temporary
duplicates are likely to occur, the conversion programs must be
generated in a different way.

• What is the cause and solution for SAP error message CNV_20200_CHECK053 - Temporary duplicates possible due to mapping of company codes &1 and &2 ?

  The SAP error message CNV_20200_CHECK053 indicates that there are potential temporary duplicates in the mapping of company codes during a data migration or conversion process. This error typically arises in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion scenarios.
  Cause:
  The error occurs when there are overlapping or conflicting mappings between two company codes. Specifically, it suggests that the system has detected that the same data (e.g., customer, vendor, or general ledger accounts) might be mapped to more than one company code, which can lead to inconsistencies or duplicates in the target system.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Review Mapping Configuration:

  Identify Duplicates:
  
  Use the tools provided by SAP to identify any duplicate entries in the mapping tables.
  Look for records that may be mapped to both company codes simultaneously.
  
  
  
  Adjust Mappings:
  
  Modify the mappings to ensure that each entity (e.g., customer, vendor) is only mapped to one company code at a time.
  If necessary, create separate mappings for different entities to avoid conflicts.
  
  
  
  Test the Changes:
  
  After making adjustments, run a test migration to ensure that the error no longer occurs and that the data is correctly mapped.
