How to find smartform that is used within a transaction

Hi experts,

Im trying to find the smartform that are used behind transaction FNVS/me22n/zab1/zapb

From me22n i know it uses zmedruck and i could find this by doing the following:

transaction nace - ef - neu. there i could find everything, even the printprogram.

this i found because someone told me you can find everything from orders there within EF.

but the other transactions i don't know how to start looking for the smartform, as i cant debug those printpreviews neither.

If someone can explain me how i can find the smartform used behind those printscreens that would help me a lot.

regards,

michael
