I probbly missed something, but I don't understand how this parameter can be used in your repeat region if it doesn't exist in the part... I don't use Pro/Intralink, but with Windchill there are some Windchill parameters called "ptc_wm_.......". The parmeter you are talking about seems to be a user-defined parameter, which can be manually created in your part. asm.mbr.DESIGNATION is a report symbol of your repeat region which calls the user-defined parameter "DESIGNATION", isn't it?
