Asynchronous ABAP proxy

Question

hello everybody!
i'm working with PI 7.1
i create a interface ABAP proxy -> PI -> file
so is a async interface.
every step was created succesfully.
When i try to call proxy from my abap program or from test tool in SPROXY transaction i don't see any message in monitor.
No file arrived, no errors in log , (SM58, ST22, SM21, integration monitor)...nothing.
i tryed to change the Service Interface and set Syncrounous mode.
so now the file is arrived!!!!!! but... i have error in message monitor because (correctly) it's expecting a return mapping.
where is the problem? can i use this scenario?
thanks!
PS: I prefere find a solution without use the sync async bridge.

Answer 1

yes of corse:
in IR
MessageType_IN
MessageType_OUT
MessageMapping between the 2 MT
a service interface SI_SP2FS_OUT Outbound and Async
a service interface SI_SP2FS_IN Inbound and Async
a Operation mapping between SI_SP2FS_OUT  and SI_SP2FS_IN
In ID
Communication Channel to FTP folder
Receiver determination with follow parameter:
sender communication Component : SAP_DEV
sender Interface : SI_SP2FS_OUT
sender namespace : http://mynamespace
receiver party : *
receiver communication Component : *
Configured receivers: FTP_DEV
Interface Determination:
sender communication Component : SAP_DEV
sender Interface : SI_SP2FS_OUT
sender namespace : http://mynamespace
Receiver Agreement:
sender communication Component : SAP_DEV
receiver communication Component : FTP_DEV
receiver Interface : SI_SP2FS_IN
receiver namespace : http://mynamespace
In R3 abap side i created proxy pointing to SI_SP2FS_OUT with SPROXY transaction.
