On my approval workflow, state one the user should select a department on the PO. There's then a transition that checks if Department = X then move on to a state that sets X as the next approver. However, can anyone suggest an error check/catch state if the department isn't one that should be allowed or approved please? I've tried an Error state so the transition here is if Department != XYZ etc AFTER SUBMIT. However, this ends in an infinite loop. Thoughts?
