Multiple start events in different lanes (BPMN notation)

Greetings everyone, I am quite new to Camunda and BPMN and have a general question about modelling a process using the BPMN notation.

I have a “Receive Invoice”-process where either the accountant or the project manager receives the invoice from a service provider. I have modelled the process as follows:

My questions are:

  • Is it possible to have two start events in different lanes of the same pool? I know it is possible to have multiple start events as stated here, but i couldn’t find any example that has them in different lanes but in the same pool.
  • Should the service provider that sends the invoice to the “Example Company” be modelled as a collapsed pool?

Many thanks in advance!

Hi @olrchhlm
Welcome to the forum

This is no problem, a land doesn’t have any kind of affect on events and gateways - lanes just indicate who is responsible for tasks.

This is completely up to you, but i would say it’s only required if it helps the readbility of the model of there is a lot of back and forth communication.


Hi @Niall, great, many thanks you for your quick response!
