Split Response without BPM

Hi,

i have a synchronous scenario:

SAP (ABAP proxy) <-> 3rd Party (http)

Is it possible to send in addtion to the (synchronous) proxy response some IDocs without use of BPM?

synchr proxy request .................-> http service

synchr proxy response...............<-

IDoc A......................................<-

IDoc B......................................<-

Regards,

Udo
