BPM Error: no interface action for sender or receiver found

Question

Dear All
I am doing an HTTP to Proxy scenario using BPM Synch Asynch bridge. The error in HTTP is error 500 (Internal Serve Error)
I am getting following error in moni
<Trace level="1" type="T">select interface namespace urn:WorkDelivery</Trace>
  <Trace level="1" type="T">--start determination of receiver interface action</Trace>
  <Trace level="1" type="T">Loop 0000000001</Trace>
  <Trace level="1" type="T">select interface LocationSynch_Abs</Trace>
  <Trace level="1" type="T">select interface namespace urn:WorkDelivery</Trace>
  <Trace level="1" type="T">--no interface action for sender or receiver found</Trace>
  <Trace level="1" type="T">Hence set action to DEL</Trace>
  </SAP:Trace>
I have seen some posts on sdn regarding the same problem but couldn't get any solution out of it.
Please let me know how can this problem be solved.

Answer 1

I am using Two Synchronous interfaces:
Synh_Out: Used before BPM
Sync_Abs inside Synch/Asynch bridge:
I am using an switch step to check a condition then in both the branches I have a send step and a transformation step:
Send step1 is using one Asynch Abstract Interface
Send step2 is using Another Asynch Abstract Interface. These Interfaces have different message types.
The Transformation step in both the branchs have same operation mapping.
The laststep after switch step is closing A/S bridge.
There are two RDs after after BPM. They are having the same Interfaces as there in the respective send steps.
I can see the xml version of my BPM
