• What is the cause and solution for SAP error message WS344 - Unexpected data record (WBRK) read from archive (internal error) ?

  The SAP error message:
  WS344 Unexpected data record (WBRK) read from archive (internal error)
  typically occurs during the reading or processing of archived data in SAP, especially when dealing with archive files or during data retrieval from the archive.
  
  Cause
  
  Data inconsistency or corruption in the archive file: The archive file being read contains unexpected or corrupted data records.
  Mismatch between the expected and actual archive file format: The program expects a certain data structure or record type but encounters a different one (here, an unexpected WBRK record).
  Incorrect or incomplete archive file: The archive file might be incomplete, truncated, or damaged.
  Version incompatibility: The archive file was created with a different SAP release or archiving object version, causing incompatibility.
  Incorrect program or object used to read the archive: The program reading the archive is not the correct one for the archive object or version.
  
  
  Explanation of the error components
  
  WS344: This is the message number.
  Unexpected data record (WBRK): The program encountered a data record of type WBRK which it did not expect at this point.
  Read from archive (internal error): The error occurred internally during reading from the archive.
  
  The WBRK record is a specific data record type related to the archiving object. Encountering it unexpectedly means the reading logic is out of sync with the archive file structure.
  
  Solution / Troubleshooting Steps
  
  
  Check the archive file integrity:
  
  Verify that the archive file is complete and not corrupted.
  Use OS tools (e.g., checksum, file size comparison) to confirm the file is intact.
  If possible, try to re-transfer or re-create the archive file.
  
  
  
  Verify the archiving object and program:
  
  Confirm that the archive file corresponds to the correct archiving object.
  Ensure you are using the correct program or transaction to read the archive.
  Check if the archive file was created with the same SAP release and archiving object version.
  
  
  
  Check SAP Notes and Support:
  
  Search for SAP Notes related to WS344 or WBRK errors.
  Sometimes SAP releases patches or corrections for archiving object inconsistencies.
  
  
  
  Recreate the archive file:
  
  If possible, recreate the archive file from the source system.
  Ensure the archiving process completes without errors.
  
  
  
  Use transaction SARA:
  
  Use transaction SARA (Archive Administration) to check the archive file.
  Use the "Check" or "Test" functions to validate the archive file before reading.
  
  
  
  Check for custom modifications:
  
  If custom code or enhancements are involved in archiving or reading, verify they are not causing the issue.
