"Fields Relevant to Printouts of Changes" for Transm. Medium = 7

Hi,

I have a serious doubt about the config "Fields Relevant to Printouts of Changes" (T166C Table).

• I defined 2 message types for PO ZOP1 & ZOP7;  ZOP1 with Transmission medium as 1 (=Print Output) and ZOP7 with 7(= Simple Mail).
• I configure few fields as Relevant to Printouts of Changes, here.
• I change a field in PO, which is not relevant for printoutput changes, ZOP1 does not trigger (as expected). but ZOP7 still triggers.

Is it standard behavior?

Does this config works only for Transmission medium = Print?

How can I control this behavior if transmission of Medium is other than "Print"?
