Hi All,
In my App. I know that I will get Sales order hedaer and items messages.
When header/Item comes I need to send response message for that.
But, once all messages for a sales order arrive I need to post that in SAP to create sales order.
Now, I may receive header initially, after that one item message may come today, another after 6 hrs, or may be next day.
So, problem is will have to wait till I browse all messages.
But, if Today I had browsed header and send its response back, Then item message comes next day, that time how will know that I had already sent response for header message?
Can I update the message headers, so that I can say using that as a flag that I had browsed it earlier/sent its response already.
Let me know ur feedback and solutions.
Thanks.

The only way that you are going to be able to update something in the message header is to get the message, make the update, and put the message back.
How you thought about using message groups? The putting application could put everything in one group. Your getting program could then get the group when all messages are available. The downside is that you don't send back the ack for the header message until all messages are available.
Another option would be to actually get the message off of the queue and put it into a database while you waited for the rest of the messages to come in. WMQI is built for things like this. |
