Workflow multi modules conditions

Hello, First, excuse my english :wink:

I try to find information linked to my problem but i did not find in the forum. If someone have a link, thank you.

My problem

  • I have three modules : A, B and C.
  • Module A and B have a N:N relatonship
  • Module B and C with an other N:N relationship.

I want to create a workflow for A with conditions based on B (it’s ok) but i need to test too a condition from C.

Is it possible ? I did not succeed to do that.
Thank you
