The first thing to check is if you have the ArcFM license set to Designer. If you don't, you will be able to see Work Requests and their designs, but Open Design won't be enabled.
Is the user in one of the Task Roles that is set in the Open Design task? To check this:
Select the Node Types tab in the PX Admin tool.
Select Design in the Node Types list.
Select Open Design in the Tasks list, click Properties.
Make sure that the role that the user is in is checked in the Task Roles list.
Also, if there is a Transition set (there usually isn't for Open Design), check the roles for that transition to make sure the user is in one of them. You can check this in the Transitions tab.
Thank you for the reply. The hints were helpful. It turned out to be a missing SubTask customization on the open task.
Great! Yes, that will certainly cause it too.
