GT302
- The key columns of table & could not be determined. ?The SAP error message GT302, which states "The key columns of table & could not be determined," typically occurs when the system is unable to identify the key fields for a specified database table. This can happen for several reasons, and understanding the cause is essential for finding a solution.
Causes:
Missing Key Definition: The table in question may not have a primary key defined in the Data Dictionary (SE11). Every table should have at least one key field to uniquely identify records.
