How servie entry sheets transfers to R/3

Hi,

Confirmations & services entry sheets will enter in the same application provided by SRM.

Confirmation can trasfer to R/3 through ALE concept with message type.

I want to clarify is service entry sheets also trasfer to r/3 thorugh ALE ? or RFC ?

message type for confirmation was MBGMCR ..

What is the message type for service entry sheets trasfer ?

Please confirm..

Thanks
