  The SAP error message CNV_10940_MSG620 indicates that certain domains have been excluded from a screen because there is no mapping data maintained for them. This typically occurs in the context of data migration or conversion processes, particularly when using SAP's tools for data migration, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  
  Missing Mapping Data: The primary cause of this error is that the system expects certain domains to have mapping data defined, but none exists. This can happen if the mapping was not set up correctly or if the relevant data was not imported or defined in the migration project.
  Configuration Issues: There may be configuration issues in the migration project that prevent the system from recognizing the necessary mappings.
  Incompatible Data Structures: The data structures in the source system may not align with the target system, leading to missing mappings.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Go to the relevant transaction or tool where the mapping is defined (e.g., the Migration Cockpit).
  Verify that all necessary mappings for the domains in question are correctly defined.
  If mappings are missing, create or import the necessary mapping data.
  
  
  
  Review Migration Project Settings:
  
  Ensure that the migration project is set up correctly and that all required settings are configured.
  Check if there are any prerequisites or dependencies that need to be addressed.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific migration tool you are using. There may be guidelines or best practices for setting up mappings.
  
  
  
  Testing:
  
  After making changes, run a test migration to see if the error persists. This can help confirm that the mappings are now correctly recognized.
