We have SAP PO 7.4 single stack working on B2B Scenarios. We will be using AS2 Adapter to send and receive ANSI X12 messages like POs inbound, Order acks Outbound, PO changes inbound etc. We installed B2B Add on ESR Content and has some sample scenarios in B2B Mapping Kit.
Scenario 1: When order received from Customer (850) we need to send Functional Acks ( Both Positive and Negative ) based on the status of success / failure of IDOC Posting. How do we achive this scenario without BPM. What is SAP recommended solution ( RDS approach) for this scenario considering its ANSI X12 850 to IDOC Orders scenario. I'm thinking of using exit in IDOC Posting fucntional module to trigger Proxy to PI which wil lbe sent to Customer after Mapping.
Along with Funtional ack ECC should send ORDRSP IDOC to PI to ANSI X12 855 as well.
Scenario 2: in another scenario, If send Order 850 to Vendor wil lthey typically send 855 as a response ? Since Its Orders IDOC outbound, how to make this as synchronous to receive 855 and update ECC with ORDRSP IDOC without BPM?
I would like to develope these scenarios avoiding BPM if possible. Since we are not implementing RDS solution, we will be developing mapping inhouse. what is the SAP standard recommended approach if you used RDS ?
Thank you
