  SAP Error Message:
  
  WY091 - Error deleting table & from database
  
  Cause:
  The error message WY091 occurs when SAP tries to delete a table from the database but fails. The placeholder "&" in the message is replaced by the actual table name during runtime.
  Common causes include:
  
  Database constraints: Foreign key constraints or dependencies prevent the table from being deleted.
  Authorization issues: The user or process attempting the deletion lacks the necessary database or SAP authorizations.
  Database locks: The table is locked by another process or user, preventing deletion.
  Technical issues: Database inconsistencies, missing database objects, or corrupted metadata.
  Incorrect or incomplete deletion process: The deletion is attempted without proper cleanup or in an incorrect sequence.
  
  
  Solution:
  
  
  Check Database Locks:
  
  Use database tools or SAP transaction SM12 to check if the table or related objects are locked.
  Release any locks if safe to do so.
  
  
  
  Verify Authorizations:
  
  Ensure the user or background job has the necessary SAP authorizations (e.g., S_TABU_DIS for table maintenance).
  Check database user permissions for dropping or deleting tables.
  
  
  
  Check Dependencies:
  
  Identify if the table has foreign key relationships or dependencies.
  Use database tools or SAP transactions (like SE11) to check table relationships.
  Remove or adjust dependent objects before deleting the table.
  
  
  
  Use Correct SAP Tools/Transactions:
  
  If deleting a custom or temporary table, use the appropriate SAP transaction or report.
  For dictionary tables, use SE14 (Database Utility) to delete or adjust the table.
  In SE14, choose "Delete database table" carefully, ensuring no dependencies exist.
  
  
  
  Check Database Logs and Dumps:
  
  Review database logs for errors during deletion.
  Check ST22 for any short dumps related to the deletion process.
  
  
  
  Consult SAP Notes:
  
  Search SAP Support Portal for notes related to WY091 and your specific database platform.
  Sometimes, specific patches or corrections are required.
  
  
  
  Technical Cleanup:
  
  If the table is a temporary or cluster table, ensure proper cleanup procedures are followed.
  For cluster or pooled tables, deletion is handled differently.
