Works Process prepick position

How can you get a robot to pick and place at a specific spot when using a Works Process? I tried making use of a prepick_Pck1 subprogam, but without succes, as the robot still goes to an undesired poistion after the prepick program before it picks up the part. Same problen for the preplace position.

See Pick and Place Tasks

check Advanced properties in works process, there you can find also pickApproach and placeApproach
