EDI – Receive Location not picking up files

I am a newbee to Biztalk.  I have an inbound  EDI304  message that is picked up from inbound folder and goes through an orchestration (to add in a couple of nodes) and is put in a folder . Then the next receive location is supposed to pickup. This pickup is not happening. the receive location type is EDI with passthru receive.

URI is EDI:\\VZN1:ZZ:VZN1

the receive location is called RL_VZN1

the receive port RP_INTER  has the receive location 

RL_VZN1   <==> EDI:\\VZN1:ZZ:VZN1

This receive port caters to multiple receive locations.

From this receive location, the next orchestration is supposed to pick it up.

The ADAPTER -> EDI is setup to have “EDI:\\VZN1:ZZ:VZN1” this combination for the EDI304.

The receive location is not picking up the files. All the ports and orchestrations are enabled. I am not sure if I am missing something here. The HAT also stops at the first sendport. No errors even in the eventlog.

Any help is appreciated.
