• What is the cause and solution for SAP error message DT644 - Transparent flag was set. Convert table ?

  The SAP error message DT644, which states "Transparent flag was set. Convert table," typically occurs during the process of converting a database table that has been defined as a transparent table in the Data Dictionary (DDIC). This error can arise during various operations, such as data migration, system upgrades, or when performing certain database operations.
  Cause:
  
  Transparent Table Definition: The error indicates that the system is trying to convert a table that is defined as a transparent table. Transparent tables are database tables that have a one-to-one relationship with the underlying database table.

  Solution:
  
  Check Table Definition: Verify the definition of the table in the Data Dictionary (transaction SE11). Ensure that the table is correctly defined as a transparent table and that its structure matches the underlying database table.
  Adjust Conversion Logic: If you are performing a conversion, ensure that the logic is appropriate for transparent tables. You may need to modify the conversion program or logic to accommodate the table type.
  Recreate the Table: If the table structure is inconsistent, consider recreating the table in the Data Dictionary and ensuring that it matches the database structure.
  Use Correct Tools: If you are using tools for data migration or conversion, ensure that they are compatible with transparent tables and that you are following the correct procedures.
