    Converge tasks dynamically

    marcosdutto Newbie

      I have this diagram:

      modelo.png

      At the beginning of the process i don't kno hoy many tasks of Solicitud i will have in runtime so i make this construction to create more than one "solicitud". The flow "otra solicitud?" is a conditional and it is apply N times.

      I want to converge two instance of the task "Solicitud" into one instance of the task "Orden". While in the diagram ther is only one flow from Solicitud to Orden in runtime there are more than one and i want to join that instances of the flow into one Orden flow.

       

       

      How can i do it? Ther is any construction that help me?

       

      Thanks

       

      Here is the .bpmn code
