Captioned User exit is meant for default values of Foreign Trade header data.
Can you please inform me, can this exit be trigerred in VF01?
I tried the same using breakpoint, but was unsuccessful. Debugging mode did not start.
I wish to default values in Billing Document Foreign Trade Data at Header & Item Level. Can you please tell me whether I am on the right track?
I don't know in this moment. I suggest you that activate it (create the project, set a break-point in the include ZX*), run VF01 and check in that moment if stop (if it stop).
