Aggregation Event not working

Hi,

I have commisioned two epcs(object event) and tried to perform aggregation event on these two epc to create a hierarchy.

It is working fine , if both have same event message extension table.

If both are having different event message tables, then aggregation event is behaving unexpectedly and not triggering rules in proper sequence.

Kindly suggest, Is it possible to perform aggregation on two epcs as parent and child having different event message extension tables??

Thanks in advance 😊
