To help identify what areas could be using the Table:
- Go to Configuration > Tables
- Highlight the Table
- Click Table Cleanup
If the table is being used in an Attribute, you can verify which ones by going to Configuration > Attributes and locate the Table name
Next, we will need to create a query in each module to identify where the table is in use. The results can be different between Admission's Office and Registrar's Office, depending on where the information is entered.
After you identify the records where the entry is in use, modify the records to utilize a different table entry. After all records have been changed, you should be able to delete the table entry without receiving the error.
