Smart SAP Assistant

• What is the cause and solution for SAP error message NSDM_MIG_CONTROL073 - Max. no. of MSEG must not be less than max. no. of MKPF ?

  The SAP error message NSDM_MIG_CONTROL073 indicates that there is a mismatch between the number of material document items (MSEG) and the number of material document headers (MKPF) during a migration or data upload process. Specifically, the error states that the maximum number of MSEG entries must not be less than the maximum number of MKPF entries. This typically occurs in scenarios involving data migration, such as when using the SAP Migration Cockpit or other data transfer tools.
  Cause:
  
  
  Data Inconsistency: The primary cause of this error is that the number of entries in the MSEG table (which contains the line items of material documents) is less than the number of entries in the MKPF table (which contains the headers of material documents). Each material document header (MKPF) should have corresponding line items (MSEG).
  
  
  Incorrect Data Preparation: If the data being uploaded or migrated has not been properly prepared, it may lead to this inconsistency. For example, if some material documents are created without corresponding line items, this error will occur.
  
  
  Data Format Issues: If the data format or structure does not align with the expected format in SAP, it can lead to discrepancies in the number of entries.
  
  
  Solution:
  
  
  Check Data Consistency: Review the data being migrated to ensure that for every MKPF entry, there are corresponding MSEG entries. You can do this by querying the source data to count the number of MKPF and MSEG entries and ensuring they match.
  
  
  Data Correction: If you find discrepancies, correct the data. This may involve:
  
  Adding missing MSEG entries for MKPF records.
  Removing or correcting MKPF entries that do not have corresponding MSEG entries.
  
  
  
  Use Data Validation Tools: Utilize SAP tools or scripts to validate the data before migration. This can help identify and rectify issues early in the process.
  
  
  Review Migration Templates: If you are using a migration template, ensure that it is correctly set up and that all required fields are populated correctly.
  
  
  Consult SAP Documentation: Refer to SAP documentation or notes related to the specific migration process you are using. There may be specific guidelines or best practices that can help resolve this issue.
  
  
  Testing: After making corrections, perform a test migration with a smaller dataset to ensure that the issue is resolved before attempting a full migration.
  
  
  Related Information:
  
  MKPF Table: This table contains the header data for material documents, including fields like document year, document number, and document type.
  MSEG Table: This table contains the line item data for material documents, including fields like material number, quantity, and movement type.
  SAP Migration Cockpit: A tool used for migrating data into SAP systems, which may provide additional logging or error messages that can help diagnose issues.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  By following these steps, you should be able to resolve the NSDM_MIG_CONTROL073 error and ensure a successful data migration process.
