How can I add field by a same field when across event

A user access our system will trigger many transcations. A transaction will generate some log, which are serval event in es and they have a same field called "globalNo". One event will log the name of the transaction and add the field "transName" .
Now I want to add the field "transName" to the events which have the same field "globalNo", how can I make it!
Thanks a lot!
