One message type to 3 receiver message types

Hi All,

I have a requirement as follows ,

I will get a request from source system and need to send it to 3 different systems in different format like IDoc ,File and RFC.

Can i use one message mapping by adding 3 message types in signature tab? like one MT at source side and 3 MT (IDoc ,File and RFC) at target side?If yes,will I get any issue while testing as there are more than hierarchy?

Cheers,
