Company code mapping values result in implicit merges. Adjust your
mapping values accordingly. You must also add company codes as source
values to the mapping if they are target values, and already exist
before the conversion. We recommend that you run the analysis again with
the updated mapping values.

• What is the cause and solution for SAP error message CNVA_20290_CHECK202 - There are implicit merges due to the mapping of the company codes. ?

  The SAP error message CNVA_20290_CHECK202 indicates that there are implicit merges occurring due to the mapping of company codes during a data migration or system conversion process. This typically arises in scenarios such as SAP S/4HANA migrations or data transfers where company codes are being consolidated or mapped incorrectly.
  Cause:
  
  Company Code Mapping Issues: The error suggests that multiple company codes are being mapped to a single target company code, which leads to implicit merges. This can happen if the mapping configuration is not set up correctly or if there are overlaps in the source data.
  Data Overlap: If the source company codes have overlapping data (e.g., customers, vendors, or financial transactions), the system may not know how to handle these overlaps during the migration.
  Configuration Errors: Incorrect settings in the migration cockpit or data transfer tools can lead to this error.
  
  Solution:
  
  Review Mapping Configuration: Check the mapping of company codes in the migration cockpit or the relevant configuration settings. Ensure that each source company code is mapped to a unique target company code.
  Data Cleansing: Before migration, cleanse the data to ensure there are no overlaps or duplicates that could cause implicit merges. This may involve consolidating data or adjusting the mapping strategy.
  Adjust Migration Strategy: If necessary, adjust your migration strategy to avoid implicit merges. This could involve creating additional target company codes or changing the way data is grouped during the migration.
  Consult Documentation: Refer to SAP documentation or guides related to the specific migration process you are undertaking. There may be specific recommendations or best practices for handling company code mappings.
  Testing: Conduct thorough testing in a sandbox or development environment to identify and resolve any mapping issues before executing the migration in the production environment.
