• What is the cause and solution for SAP error message CNV_20700065 - All material numbers present in MARA are assigned in the mapping ?

  The SAP error message CNV_20700065 indicates that all material numbers present in the MARA table (which contains general data for materials) are already assigned in the mapping during a data migration or conversion process. This typically occurs in the context of using SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion tools.
  Cause:
  
  Mapping Issues: The error suggests that the system has detected that there are no unassigned material numbers left for mapping. This could happen if all materials have already been mapped to a new structure or system.
  Data Overlap: If the source and target systems have overlapping material numbers, it may lead to this error if the mapping is not set up correctly.
  Configuration Errors: There may be issues in the configuration of the migration tool or the mapping process that prevent new mappings from being created.
  
  Solution:
  
  Review Mapping Configuration: Check the mapping configuration to ensure that it is set up correctly. Make sure that there are indeed material numbers that need to be mapped and that they are not already assigned.
  Check for Duplicates: Look for duplicate material numbers in the source data that may have already been mapped. If duplicates exist, you may need to resolve these before proceeding.
  Adjust Mapping Logic: If necessary, adjust the logic used for mapping materials. This may involve modifying the mapping rules or criteria to allow for additional mappings.
  Data Cleansing: Perform data cleansing on the source data to ensure that there are no unnecessary or erroneous entries that could be causing the issue.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be specific guidelines or troubleshooting steps provided for this error.
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific scenario.
