  Meaning / Cause:
  This error occurs during the update of the time series buffer in SAP, specifically when the system tries to update or post data related to a particular posting period and variant.

  Buffer overflow or corruption: The time series buffer might be corrupted or full, causing update failures.
  Authorization issues: The user or process attempting the update lacks the necessary permissions.
