When you edit the subsection if there is a delete permission button instead of a create permission button this means a permission is already assigned. If you cannot find the permission, please contact us to get the name of the permission for you.
You can create a permission by following the steps below:
Find the subsection in organisation structure and click into it.
Click Edit Subsection and then click again Edit.
Click Create Permission then click Yes.
Click Save.
📌Note: Please search for the subsection permission again. If you can't find it make sure you are filtering the permission search correctly. If after filtering the permissions, you still cannot find it, please contact us.
