I have created an attribute in the Service Case entity called 'Resolved On'. Its is a datetime field. When a case is resolved, I want this field populated with the date and time that the resolution occurred. I would prefer if it populated this field by copying the date/time from the "Created On' field of the associated Case Resolution activity, but could settle for it being the current date time.
I tried to do this via a workflow, but found that a) you cannot modify the Resolved On field because the case is closed and now read-only and b) you can't select the date field in the resolution activity to copy the date from!
Does anyone have any suggestions on how I could populate this Resolved On field with the date/time of case resolution? I'm not much of a programmer, but I might be able to do some simple scripting if I have examples to follow.
