• What is the cause and solution for SAP error message CRD_MDA199 - External assignment ID &1 was used more than once ?

  The SAP error message CRD_MDA199 indicates that an external assignment ID has been used more than once in a context where it is expected to be unique. This typically occurs in scenarios involving data imports, such as when uploading master data or transactional data into the SAP system.
  Cause:
  
  Duplicate External Assignment ID: The primary cause of this error is that the same external assignment ID is being referenced multiple times in the data being processed. This can happen if the data source contains duplicates or if the data is incorrectly formatted.
  Data Import Process: During data import processes (like LSMW, BAPIs, or IDocs), if the same external ID is used for different records, the system will raise this error to prevent data inconsistencies.
  
  Solution:
  
  Check Data Source: Review the data source from which you are importing the data. Look for duplicate entries of the external assignment ID and remove or correct them.
  Data Cleansing: If duplicates are found, you may need to cleanse the data to ensure that each external assignment ID is unique before attempting the import again.
  Modify Import Logic: If the data is being generated programmatically, ensure that the logic used to create external assignment IDs guarantees uniqueness.
  Use Different IDs: If the same external assignment ID is necessary for different records, consider using a different ID for each record to avoid conflicts.
  Testing: After making the necessary changes, test the import process with a smaller dataset to ensure that the error does not occur again.
