1. Open the employee profile and navigate to a section containing a field which is mapped to a custom MDF object configured.
2. Make sure the mapped MDF has the setting of Secured=No.
3. Click the detail button or add new button of the field.
4. Observe that the system shows a permission error.

After 1H 2026, the security has been enhanced for non-secured MDF object.

When accessing or modifying an associated MDF object from another MDF object, the permission "access to non‑secured object" will be required if the associated MDF is a non-secured object(Secured=No). 

If you would like to keep the MDF as non-secured temporarily, grant the Role‑Based Permission "access to non‑secured object" to the relevant permission role and users.

Best Practise: recommend to change the affected MDF object configuration to Secured=Yes.

1. After setting Secured=Yes, grant appropriate View and/or Edit permissions to the object based on business needs via Role‑Based Permissions.
2. Test with a user in scope to confirm the value help opens as expected and permissions are enforced as designed.
3. Plan to migrate away from non‑secured objects to ensure compatibility with the latest employee profile.
