how to use start event message

Does start event message only displays the input message from the pools? (or is it also used for the input message from the another lanes?)

You must consider "message" in a very, very wide meaning.

In fact it is better to consider the content of the message : datas (i.e customer id), other informations (i.e customer name, etc.), amount of money, ...

As the message can contain one or several of these, the proper item can be "forwarded" to the 1st activity of the swimlane waiting for it.

If the content is always the same (i.e Z AND W) , use a + gateway, if not (Z OR W) use a o gateway.
