  The SAP error message DRD001, which states "Lock on table &1 could not be set for plant &2," typically occurs in the context of data processing where a lock is required on a specific database table for a particular plant. This error can arise in various scenarios, such as during data updates, batch processing, or when multiple users or processes attempt to access the same data concurrently.
  Causes:
