re: exits

HI,

I want to update one field doing some data process ,before going to save po in me23n. I tried to create the field exit to update the incoterms in the po screen.

I could able to create field exit and activated. But it is not showing in the field exit report, to add the exit to corresponding screens while i run rsmodprf. Is there any reason.

rgds
