• What is the cause and solution for SAP error message CNV_20200_CHECK127 - No company code mapping provided ?

  The SAP error message CNV_20200_CHECK127 indicates that there is no company code mapping provided in the context of a data migration or conversion process. This error typically arises during the execution of a migration project, particularly when using SAP's data migration tools or during the implementation of SAP S/4HANA.
  Cause:
  The error occurs when the system expects a mapping between the source company codes (from the legacy system) and the target company codes (in the SAP system) but cannot find any defined mappings. This can happen due to:
  
  Missing Configuration: The company code mapping has not been set up in the migration tool or the relevant configuration settings.
  Incorrect Data: The data being processed does not have the necessary mappings defined, or the mappings are incorrectly specified.
  Migration Tool Issues: There may be issues with the migration tool itself, such as missing or incomplete data.
  
  Solution:
  To resolve the CNV_20200_CHECK127 error, you can follow these steps:
  
  
  Check Company Code Mapping:
  
  Go to the relevant transaction or configuration area where company code mappings are defined (e.g., transaction code OBY6 for company code settings).
  Ensure that the mappings between the source and target company codes are correctly defined.
  
  
  
  Define Missing Mappings:
  
  If mappings are missing, create the necessary mappings between the legacy company codes and the SAP company codes.
  Ensure that all required company codes from the legacy system have corresponding entries in the SAP system.
  
  
  
  Review Migration Settings:
  
  Check the settings in the migration tool you are using (e.g., SAP S/4HANA Migration Cockpit, LSMW, etc.) to ensure that the company code mapping is correctly configured.
  Make sure that the mapping file or configuration is correctly uploaded and activated.
  
  
  
  Test the Migration:
  
  After making the necessary changes, run a test migration to verify that the error has been resolved and that the mappings are functioning as expected.
