Hi guys I'm trying to identify a solution about following 'scenario': - Change lifecicle management: I'm modelling a workflow based on a specific workorder (type 'approval') to modify the change's state on the workorder's state change. Modifying this workorder would be available only to itsm-change-manager group. - I would introduce operational workorder (type workorder), linked to a change, where describe the operation needed to implement the change - The last workorder type would be assigned to a 'basic' agent (only itsm-change group assignment), but that basic agent would be able to change the agent's assignment, routing the work to another collegue. So if I enable some 'basic' agent to take the workorder (or change the assignement) listing their id into the ITSMWorkOrder::TakePermission::List parameter, they will be able to take also the 'approval' workorder, but I would avoid it, of course. I'm investigating ACL's to solve the problem, but after read the documentation, I didn't find any reference to change or workorders, it seems only ticket's attributes could be used. So I'd like to know if I can use ACL on change and workorders or not, or if someone has an alternative solution to meet my requirements. best regards -- * Stefano Boccanera*
