pattern, adding an inclusive gateway split activity and a complex gateway merge activity.
Since I want to send a request to all three suppliers I will change the complex gateway pattern to
"Parallel and Complex". You can do so by right-clicking on the inclusive split activity and choosing from
the context menu "Change Gateway configuration to -> Parallel and Complex".
To simulate a supplier's request for quotation I used a human task component. I created a single human
task for all three suppliers accepting all the defaults and just changing the human task title for each case.
I created three user tasks on the process creating default sequence flows from the parallel split activity
to all three user tasks and from each user task a default activity to the complex gateway merge activity.
You should notice that there is a warning on the complex gateway merge activity that the expression
from node is empty. If you go to the implementation details of the complex gateway activity you will see
that you can define either a simple or an xpath expression to control, by selecting the "Abort pending
