ccBPM issue...for IDOC collection

Hi All,

we are facing issue with ccBPM, we are in PI 7.3 dual stack.

we have scenario, where we have to collect IDOCs from ECC and send them as one message to target.

issue is i have defined the BPM logic as below, but the problem is container element is collecting but it is not coming out of the loop, result is it is waiting for some other IDOCs to come, if we trigger one more this one also going to collect and not coming out of loop.

since we have defined control branch, the process is cancelling after specified time.

can any one throw some light on this issue.
