(GAIA_FI06)

Cause and solution
The field cannot be deleted since deleting it will result in duplicate conditions in the Permissions for Records setting.

Example: In the case where the following record conditions are set in the Permissions for Records setting

• "Personal Information" field = "Yes", and "Department" field = "Sales"
• "Personal Information" field = "Yes", and "Department" field = "Human Resources"

If you delete the "Department" field, the field is removed also from the conditions set in the Permission for Records setting.
Since this would result in duplicate conditions being set for the "Personal Information" field, an error will appear.

1. Reload the form settings screen.
   Changes made to the app form are discarded and it returns to the state when it was last saved.

2. Click on the App Settings tab, click Records under Permissions, and then modify the Permission for Records setting.

   Check the record conditions set in the setting, remove items related to the field to be deleted, and specify the conditions in such a way that there is no duplicate condition.
