Problem in Inbound IDOC

Dear Expert,

I need one more helo from ur side:

Kindly help me as i am facing one problem in IDOC, suppose i have one function module which is triggering inbound IDOc and inside that function module calling another function module and inside that function module one incliude program(user exit) is used and this include program is performing some validation check and if validation check is not fulfilled then error will be displayed from 'MESSAGE e035(yuco) WITH i_mseg-matnr zzbwkey.'

As it is already told by every one that it will be displayed in staus of IDOc but now my question is:

From where it will Exit either only from include program where this MESSAGE e035(yuco) WITH i_mseg-matnr zzbwkey is used or from the function where this include program is used

or from the main function which is used for inboud idoc.

Warm Regards

Shelly Malik
