SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20600_CHECK - Messages for Check classes

• Message number: 057

• Message text: Temporary duplicates possible due to mapping of company codes &1, &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 for number assignment &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_20600_CHECK057 - Temporary duplicates possible due to mapping of company codes &1, &2 ?

  The SAP error message CNV_20600_CHECK057 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 company codes in the source and target systems. Specifically, it suggests that the same company code might be mapped to multiple entries, leading to ambiguity in the data migration process. This can happen due to:
  
  Duplicate Entries: The same company code is mapped to different entities in the target system.
  Incorrect Mapping: The mapping configuration may not be set up correctly, leading to conflicts.
  Data Integrity Issues: There may be issues with the source data that cause conflicts during the mapping process.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Review Mapping Configuration:
  
  Check the mapping of company codes in the migration tool. Ensure that each company code in the source system is uniquely mapped to a single company code in the target system.
  
  
  
  Identify Duplicates:
  
  Look for duplicate entries in the mapping table. You can use SQL queries or data analysis tools to identify any company codes that are mapped more than once.
  
  
  
  Correct Mapping:
  
  Adjust the mapping to ensure that each company code is mapped correctly and uniquely. If necessary, consolidate or split mappings to eliminate duplicates.
  
  
  
  Data Cleansing:
  
  If the source data contains duplicates or inconsistencies, perform data cleansing to resolve these issues before attempting the migration again.
  
  
  
  Testing:
  
  After making changes, run a test migration to ensure that the error does not occur again and that the data is being mapped correctly.
  
  
  
  Consult Documentation:
