The "Edit" action has been made available for Promotion Objects from PDMLink 11.0 M030 (CS19603). By default, admins and the owner of the Promotion Request are able to perform the edit. The problem for us now is that there is no way to restrict whenthe owner can perform the edit. We cannot have the owner add/remove promotion objects whenever they want. It must be restricted to the certain nodes such as Rework or perhaps by a custom lifecycle state.
I have created a case with PTC and they concluded it is not possible. Please add this functionality to restrict whenthe owner can edit promotion objects either by workflow node or by lifecycle state (through Policy Administration).
