• What is the cause and solution for SAP error message DT034 - Table type changed from &->& (Table is created in the DB) ?

  The SAP error message DT034 indicates that there has been a change in the structure of a database table that is already created in the database. This typically occurs when there is a mismatch between the data dictionary definition of a table in the ABAP Dictionary (SE11) and the actual structure of the table in the underlying database.
  Cause:
  
  Change in Table Structure: The most common cause of this error is that the structure of the table has been modified in the ABAP Dictionary (e.g., adding or removing fields, changing data types) after the table was already created in the database.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production) and the transport did not include the necessary database changes, this error can occur.
  Manual Changes: If someone manually altered the database table outside of SAP (e.g., using SQL commands), it can lead to discrepancies between the ABAP Dictionary and the actual database structure.
  
  Solution:
  
  Check Table Structure: Use transaction SE11 to check the current structure of the table in the ABAP Dictionary. Compare it with the actual structure in the database using transaction SE14 (Database Utility).
  Adjust the Database Table: If the database table structure is incorrect, you may need to adjust it. This can be done by:
  
  Using transaction SE11 to modify the table structure and then activating it, which should synchronize the ABAP Dictionary with the database.
  If the table is already created in the database, you may need to use transaction SE14 to adjust the database table to match the ABAP Dictionary.
  
  
  Recreate the Table: If the table is not critical and can be recreated, you can drop the existing table and create it again from the ABAP Dictionary.
  Transport Changes: Ensure that all necessary transports are correctly applied and that the database changes are included in the transport requests.
  Check for Manual Changes: If manual changes were made to the database, revert those changes or adjust the ABAP Dictionary accordingly.
