I am trying to build a correlation using ebXML headers i.e. conversionID and RefToMessageID. I followed this blog and I managed to get some parts to work but am failing when trying to add a ReftoMessageID based on the format of the replyToMessage=RefToMessageID:ConversationID. This is the link I followed:
So you are setting the conversation id (@100) correctly but first part will be the message id which your B2B generated for the inbound message. Just open the Business Message Report of request message received at GlobalChips side, and note the value of "Message Id" (it will be in similar to 0AF1628E13D2617A3D800000314DDCC1-1). Then put it in the first part and you should be good to go.
