I have a XML message which I want to change it to three IDOCs.I have created the "In process" and "Waiting" queues .They all are grouped with the groupiId. I have to send the messages to SAP.This flow is done.
Then SAP will reply with a XML message to follow processing the IDOCS located in the waiting queue.
The problem I have is how I can make a second flow in MQSI to read the reply from SAP and get the groupid from the waiting queue and send it again to SAP.
Thanks and regards. |

I am not clear on the following:
Is the XML reply Message from SAP is for every IDOC message?
Suppose, if three idocs are sent to SAP and SAP replies with 3 XML reply messages or just one XML reply message for 3 IDOCS.
Why do you want to read the reply from SAP and get groupid from the waiting queue and send it again to SAP? |

alfonso_1973,
Here is what I understand from your post ...
You are getting single XML message, which you are transforming into 3 IDOCs. First IDOC is sent as request message to SAP. Second and third IDOC message is stored on "In Process" and "Waiting" queues respectively. After you get the reply from SAP for first IDOC request message, you need to send second IDOC request message to SAP, which is retrieved from "In process" queue?? is this correct??
Based on this assumption ... Let's say you have created your first message flow (MF1), which does following processing:
1. Transforms single input XML message to 3 IDOC.
2. Sends first IDOC to SAP. Writes second IDOC to "In process" queue. Writes third IDOC message to "waiting" queue.
Now, you need to create another message flow (MF2), which gets first reply message from sAP. Based on Group-Id in reply message, it will retrieve second IDOC message from "In Process" queue. To do this, you will have to modify MQGet plug-in node to retrieve message by Group-Id. Current version of MQGet node can only retrieve message for matching MsgId and CorrelId. Message Flow 1 and 2 works in asynchronous mode.
Similarly, you will create another message flow (MF3), which gets second reply message from SAP and retrieves third message from "waiting" queue with matching Group-Id.
