• What is the cause and solution for SAP error message NSDM_MM_MIG094 - MATDOC_EXTRACT already contains records ?

  The SAP error message NSDM_MM_MIG094 indicates that the data extraction process for material documents (MATDOC) is encountering an issue because the target table or data structure already contains records. This typically occurs during data migration or extraction processes, particularly when using the SAP Data Migration (NSDM) tools.
  Cause:
  
  Duplicate Data: The most common cause of this error is that the extraction process is attempting to insert records into a table that already has existing records. This can happen if the extraction is run multiple times without clearing the previous data.
  Incorrect Configuration: There may be a configuration issue in the data migration settings that is causing the system to attempt to insert data that already exists.
  Data Consistency Issues: If there are inconsistencies in the data being extracted or if the extraction process is not properly aligned with the data model, it can lead to this error.
  
  Solution:
  
  Clear Existing Records: Before running the extraction process again, ensure that the target table (MATDOC_EXTRACT) is cleared of any existing records. This can typically be done using a delete operation in the database or through the appropriate SAP transaction.
  Check Extraction Logic: Review the extraction logic to ensure that it is set up correctly and that it is not attempting to insert duplicate records. This may involve checking the selection criteria or filters used in the extraction process.
  Run in Test Mode: If possible, run the extraction in a test mode to see if the issue persists. This can help identify if the problem is with the data or the extraction process itself.
  Consult Documentation: Refer to the SAP documentation for the specific data migration tool you are using. There may be specific guidelines or best practices for handling this type of error.
