status of message in sync-async brige

Hi Experts,

I have a requirement in which, PI is consuming WS(sync) from third party and sending it back to ECC system(adapter not decided yet)

but in addition to it, customer wants that 3rd party system should get a response back, detailing if message has been processed by PI system or not, without getting ECC involved

so basically its like ws(sync)<..>PI ..>ecc(asyn)

Is it Possible to know status of messgae?

I know just abt sync async bridge

Pls note PI system is at 7.31

Thanks
