Re: BPM Help

Question

Hello! ALL
I am trying to develop a BPM which would send a asynchronous I/B shipment request message proxy message to SAP ECC (message coming form Sender will be transformed to Shipment Request Proxy) and once this proxy is processed. SAP ECC would asynchronously push a O/B shipment response to the i/b shipment proxy, which the BPM should receive in order to send a confirmation back to sender system that shipment request was created.
Since, this is a asynchronous request and response , the Shipment_Number which is part of the request and comes back in the response needs to be used to correlate the messages. And send the Shipment_Number back to sender confirming Shipment_Request was created.
It would be very helpful, if you can provide an idea this can achieved a BPM.
What will be the steps involved to send and then receive the response back for the message containing the Shipment number asynchronously by leveraging the Shipment Number to correlate.
Also, would like to make this all part of the block so that if the response for a shipment does not come back in a set time like within 10 mins, we will fail the block and terminate the BPM.
Please, do suggest the steps and logic needed to design the BPM with this requirement
Appreciate all the help!
Thank you so much,

Hi Abhishek
Thank you so much for the detailed explanation on the BPM steps to be used.
I have followed the steps you have suggested and faced 3 issues I need your help and advice on:
1. Was a able to get the first receive and send working (so the message went to ECC) and for the next receive and send I have the following error:
<SAP:Code area=&quot;BPE_ADAPTER&quot;>MESSAGE_NOT_USED</SAP:Code>
  <SAP:AdditionalText></SAP:AdditionalText>
  <SAP:Stack>Message <b>interface</b> is not used by <b>this</b> process</SAP:Stack>
  <SAP:Retry>M</SAP:Retry>
  </SAP:Error>
2. Also, would you suggest the Receive &#38; Send to be in block and have a inner block which has the second receive and send (and the control step will fail the whole inner and outer block). The reason I was thinking of this as similar to Shipment Request I will also need to add Freight Request block which is exactly the same service interface as shipment request only message content and transformation would be different (in the same BPM). If the Flag is Y for Shipment Request it need to go to block 1 &#38; Flag is N for Freight request it needs to go to block2.
BLOCK1 (Shipment Request =Y)---> Rec1 Transform Send1 {Inner BLOCK?Rec2 transform Send2}
BLOCK2 (Shipment Request =N)---> Rec1 Transform Send1 {Innrer BLOCK?Rec2 transform Send2}
Question:
-Do we need to have the second step in a inner block which will have the control step?
-Also how <b>do</b> i route the message between the 2 block, can I use a fork or <b>do</b> I need to have one more receive step before the routing to the 2 blocks.
3. Also, if we do not receive a asynchronous response  to the Shipment or Freight request for the second receive step, apart from failing I need to populate the send structure with Shipment_Number and the Status file = FAIL in the response going to Sender system.
Question: how <b>do</b> i populate the response structure with <b>default</b> value and the shipment number associated to the failed receive step 2 (need to save shipment number); so as to populate the response with defaults status as FAIL to the associated Shipment_Number for which the control step fails on timeout.
Thanks again!! Your response was very helpful, hoping to get past this error and add the next steps to the BPM.
Thank you,
Ritu
