SAP Error Message - Details

• Message type: E = Error

• Message class: GT - Database utilities

• Message number: 630

• Message text: Table & and temporary table & exist on the database

What causes this issue?

The original table and a temporary conversion table both exist on the
database.

System Response

Resetting will be terminated.

How to fix this error?

Check which table should not exist. If step 2 of the conversion is
already complete, the temporary table should exist. The existence of the
original table on the database is then no longer correct. If the table
is empty and the QCM table exists with data, you can delete the original
table from the database.
If data exists again in the original table, you must handle this before
you delete the table. If you are unsure, open a problem message at
BC-DWB-DIC.

• What is the cause and solution for SAP error message GT630 - Table & and temporary table & exist on the database ?

  The SAP error message GT630 indicates that there is a conflict between a table and a temporary table in the database. This typically occurs when a temporary table with the same name as a database table is created during a session, leading to ambiguity in the database operations.
  Cause:
  
  Naming Conflict: A temporary table is created with the same name as an existing database table. This can happen if a program or transaction creates a temporary table without checking if it already exists.
  Session Scope: Temporary tables are session-specific, and if multiple sessions are trying to create or access a temporary table with the same name, it can lead to conflicts.
  Database Locking: If a transaction is holding a lock on the database table, and another process tries to create a temporary table with the same name, it can lead to this error.
  
  Solution:
  
  Rename Temporary Table: Modify the code to ensure that temporary tables are created with unique names. This can be done by appending a session identifier or timestamp to the temporary table name.
  Check for Existing Tables: Before creating a temporary table, check if it already exists in the session. If it does, drop it or use it instead of creating a new one.
  Use Unique Naming Conventions: Establish a naming convention for temporary tables that reduces the likelihood of conflicts with existing database tables.
  Review Code Logic: Review the logic in the ABAP program or transaction that is causing the error to ensure that temporary tables are being handled correctly.
  Database Cleanup: If temporary tables are not being dropped after use, ensure that the cleanup logic is implemented to remove them at the end of the session.
  
  Related Information:
  
  Temporary Tables in SAP: Temporary tables are often used in ABAP programs to store intermediate results. They are session-specific and should be managed carefully to avoid conflicts.
  Database Transactions: Understanding how database transactions work in SAP can help in diagnosing issues related to locking and table access.
