Receiver Determination: No Receiver Could be Determined, but sender agreement test with OK

Hi gurus,

I`m newbee to PI, i created a pingpong scenario, ERP1->PI->ERP1.

All the objects seems already created, and i test sender agreement, all successfully, 'sender agreenment' with ok, 'receiver determination' with ok,

'interface determination&mapping' with ok, 'receiver agreement' with ok.

But when i send data from ERP, i can clearly see in SXI_MONITOR the status is successfully, means sender is ok.

Then i go to PI SXI_MONITOR, there is a error with 'Receiver Determination: No Receiver Could be Determined'.

Maybe it`s easy to you, but a little hard to me, thanks your advise.

regards,

Archer
