Our FR5 handover skips the routine that decides which plate recipe runs

I followed our handover screenshots and reached a call to a routine which is not pictured anywhere. That routine apparently chooses the external inspection recipe for our reference plate. The original integrator is still available, so I have asked for the matching program export and revision details. What I need from the walkthrough is the reason each recipe is chosen, including the fixture assumptions and ordinary PLC conditions. How would you structure that conversation so I leave understanding a real example, rather than owning a larger collection of screenshots?
