• What is the cause and solution for SAP error message TG305 - DROP of tables completed (if successful is to be checked) ?

  The SAP error message TG305 indicates that a DROP operation on database tables has been completed, but it also suggests that you should verify whether the operation was successful. This message typically arises in the context of database management within SAP systems, particularly when dealing with table deletion or modification.
  Cause:
  
  Database Operation: The error message is generated after an attempt to drop one or more database tables. The operation may have been initiated through a transaction or a program that modifies the database schema.
  Permissions: The user executing the DROP command may not have the necessary permissions to perform the operation, leading to a partial or unsuccessful execution.
  Dependencies: The tables being dropped may have dependencies (like foreign key constraints) that prevent them from being deleted successfully.
  Database Locking: Other processes may be locking the tables, preventing the DROP operation from completing successfully.
  
  Solution:
  
  Check Execution Log: Review the execution log or the system log (transaction SM21) to see if there are any additional error messages or warnings that provide more context about the operation's success or failure.
  Verify Table Existence: Use transaction SE11 (Data Dictionary) or SE16 (Data Browser) to check if the tables still exist in the database after the DROP command was executed.
  Check Permissions: Ensure that the user executing the DROP command has the necessary authorizations to perform this operation. You may need to consult with your SAP Basis or security team.
  Review Dependencies: If the tables have dependencies, you may need to drop those dependencies first (e.g., foreign key constraints) before attempting to drop the tables again.
  Database Locks: Check for any locks on the tables using transaction SM12. If there are locks, you may need to wait for the locks to be released or resolve the locking issue.
  Database Consistency: If the operation was partially successful, you may need to run consistency checks or repair operations on the database to ensure that it is in a stable state.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11 (Data Dictionary), SE16 (Data Browser), SM21 (System Log), and SM12 (Lock Entries).
  SAP Notes: Check SAP Notes for any known issues related to the TG305 message or the specific tables you are working with.
  Database Administration: If you are not familiar with database administration tasks, consider involving your SAP Basis team or a database administrator to assist with the operation.
  Backup: Always ensure that you have a backup of your database before performing destructive operations like dropping tables.
  
  By following these steps, you should be able to diagnose the cause of the TG305 message and take appropriate action to resolve the issue.
