The SAP error message DA477 indicates that there is no dictionary definition found for a secondary index associated with a specific table. This typically occurs when the secondary index is either not defined in the Data Dictionary or has been deleted or not activated properly.
Cause: Missing Secondary Index: The secondary index may not have been created for the specified table. Inactive Index: The index might exist but is not activated. Transport Issues: If the table or index was transported from another system, it may not have been properly imported. Database Issues: There could be inconsistencies in the database that prevent the index from being recognized. Development Environment: If you are working in a development environment, the index may not have been created yet.
Solution: Check Index Definition: Go to the Data Dictionary (transaction SE11). Enter the table name and check if the secondary index is defined under the "Indexes" tab. If it is missing, you will need to create it. Activate
