Ordered Events in MT

I have an event being triggered from Event Analytics and processed using a MEC map in a MT environment. Occasionally I get an issue with events for the same item being processed concurrently and out of order. Is there anyway that I can ensure events are ordered in multi-tenant?

Greetings;

According to the documentation, delivery order is not guaranteed. This is from the ION Development guide.

Message sequence
Delivering messages in sequence is not guaranteed. Only delivery is guaranteed (at least once). In
some cases the sequence of receiving is the same as the sequence of sending, but you cannot rely
on this. Many factors can impact the sequence, such as:
• Parallel processing (multi-threading).
• Documents traffic.
• Intermediate steps in the process, such as content-based routing, filtering or mapping ...

I think Sams is speaking about events generated by M3BE and sent to IEC, not by BODs distributed by ION.

Can you give an example to help us understand your problem ?

Have you tried to create a 'single thread' channel from Partner Administrator?

Rene,

How can we handle the inbound bod from ION in a sequential order using the channel ION-M3_In_Custom_Ordered. Do we need to make changes in the IEC page or in the MEC mapper?

Have you tried 'single thread' (see below sample)?

Then you should be able to control the priority for each Event as per below to ensure that they are executing in the correct order.

This example is a "low priority", meaning anything with a priority between 0 and 8 should execute before this one.

Hopefully this helps.

Rene,

Thanks for your reply...

I have done this many time in the Partner Admin tool. But for the First time I have been trying to handle this in Multi-Tenant Cloud Suite. Any I am able to manage to do this in MT. Once again Thank You for the reply.

Thanks
