Perm Level Error
While customizing rules in the Permission Manager, you might receive an error message saying:
For Website Manager (or any other role) at level 2 (or another level) in Customer (or any other document) in row 8: Permission at level 0 must be set before higher levels are set.
Error message indicates the problem is in the existing permission setting for this document.
For any role, before assigning permission at Perm Level 1 or 2 (and so on), permission at Perm Level 0 must be assigned. The error message says that the Website Manager has been assigned permission at Perm Level 1 and 2, but not at level 0. You should first correct the permission for Website Manager's role by:
Assigning permission to System Manager at level 0.
By removing permission at level 1 and 2.
After executing one of the above steps, you should be able to successfully add new permissions rules in the Role Permission Manager.
