Open UDC application P0004A, fill with H90 and FP the two fields.
Put ADD and go to the end of the grid set the fast pah that you want to use, set the (task view:name of task) and after valid
logoff and log on and after try your pastpath
As Zoltan said, absent any other setup, FP will try to execute the ZJDE0001 version, but I don't know what happens if that version doesn't exist. But fyi, if you NEED a different version to be called, you can add a P4210 entry to 00/FP, pointing to a SelectionNumber/MenuID, and that entry will take precedence over the system calling the generic version.
