BPM NOT WORKING

Hi everybody.

I have the next bmp

Step 1: Receive asyn

Step 2: Send sync

Step 3: Send async

Step 4: Stop

In the step 2 a webservice is consumed. Im using a SOAP Receiver adapter.

The problem is than this step is never executed, the message get into the bpm but this syncronhous call iis never done or I least I can't see it. I can't see any message in adapter engine.

In sxi_monitor I just can see the message between the sender system and BPM....

What could be the problem?

Thanks a lot
