I have a Z function Group. Inside this FG, a subscreen is created with only 1 element, push button. On the PAI of this screen, a standard function module is called. This Z function group is called as a screen exit of some standard SAP transaction (unknown to me).
My doubt is: How do I find where this screen is called, which transaction / screen?
I tried 'Where-used list' of the screen, no results are found.
Can somebody please help.
