BPM :: n To 1 Collected Payload Pattern issue

Question

Hi
I am working on following scenario -->
Web Page --> HTTP Adapter --> XI with BPM ( Using n To 1 Payload Pattern ) --> RFC Adapter --> SAP R/3 --> XI With BPM --> File Adapter --> Legacy System with Response from RFC
Now everything is configured & when first time I executed the scenario it gives me " Green Flag " under Outbound Status for interface from Web Page to XI. Also date format error in next 2 messages. So I corrected the date format & execute it again.
But since from than I am getting " <b>Red Flag</b> " ( <i>Message has error status on outbound side</i> ) under Outbound status. I checked my BPM under MONI also & all the mapping & configuration is fine. Even I made the Overall messages as 1 but still getting the same error.
I am able to see the correlation ID of message also.
Pls. suggest.

Hi
My Scenario is working now & I am able to correlate the payloads on Vendor Name. But I need to clarify the concept of n:1 Pattern.
In my multi-mapping occurence of source message is 0 to N & Target message is 1. Now when I am sending the message in this format ( coming from web page when i am clicking the SUBMIT button two times ) :
<p3:PurOrder_Request_MT xmlns:p3="http://BpmCollectMsg:AsyncSync:AlertMgt">
         <Total_Msgs/>
         <HEADER>
            <DOCDATE/>
            <VENDOR/>
         </HEADER>
         <ITEMS>
            <PURMAT/>
            <NETPRICE/>
            <UNIT/>
            <PRICEUNIT/>
         </ITEMS>
         <Items_Schedule>
            <QUANTITY/>
            <DELIVERYDATE/>
         </Items_Schedule>
      </p3:PurOrder_Request_MT>
<p3:PurOrder_Request_MT xmlns:p3="http://BpmCollectMsg:AsyncSync:AlertMgt">
         <Total_Msgs/>
         <HEADER>
            <DOCDATE/>
            <VENDOR/>
         </HEADER>
         <ITEMS>
            <PURMAT/>
            <NETPRICE/>
            <UNIT/>
            <PRICEUNIT/>
         </ITEMS>
         <Items_Schedule>
            <QUANTITY/>
            <DELIVERYDATE/>
         </Items_Schedule>
      </p3:PurOrder_Request_MT>
I am getting results in same format means two different nodes of " PurOrder_Request_MT ".
But I was expecting results in this format ::
<p3:PurOrder_Request_MT xmlns:p3="http://BpmCollectMsg:AsyncSync:AlertMgt">
         <Total_Msgs/>
         <HEADER>
            <DOCDATE/>
            <VENDOR/>
         </HEADER>
         <HEADER>
            <DOCDATE/>
            <VENDOR/>
         </HEADER>
         <ITEMS>
            <PURMAT/>
            <NETPRICE/>
            <UNIT/>
            <PRICEUNIT/>
         </ITEMS>
      <ITEMS>
            <PURMAT/>
            <NETPRICE/>
            <UNIT/>
            <PRICEUNIT/>
         </ITEMS>
         <Items_Schedule>
            <QUANTITY/>
            <DELIVERYDATE/>
         </Items_Schedule>
      <Items_Schedule>
            <QUANTITY/>
            <DELIVERYDATE/>
         </Items_Schedule>
      </p3:PurOrder_Request_MT>
As in target they are coming as two different payloads & I am calling the RFC one time only. RFC is taking the data of first payload only. Right now my scenario is working more as creating a batch of payloads who has same Vendor Name. But my RFC doesn't take batch of payloads.
Can you pls. explain what exactly the n:1 pattern means.
Best regards
