Hi,
I have a requirement to create an MQ message group within a flow (2.1) from a single input message. I can set the required flags and sequence number within the MQMD, but what about the group id? I would like MQ to handle this, can I leave this blank and when the message is put MQ will fill it in? If not, can I use the UUID function as a group id?
Cheers,
Fazz |

Fazz,
I think the uuidasblob function should be suitable.
Once point to watch is that this function returns a value that is smaller than that required for a Group_Id, so you need to pad. Try:
| Code: |
| set OutputRoot.MQMD.GroupId = uuidasblob || x'0000000000000000'; |
I think another option would be to set the Group Id to the Msg Id of the first message in the group. |

Cheers John, I like the sound of using the message id of the original input message, that will also add some kind of audit trail.
Thanks Again,
Fazz |
