Question

Gateway for merging the flow of 1 to N pathways.

Hello!

I have a requirment to have a complex gateway connected to 15 tasks star some  those tasks, finish them, then end the process.

I am trying to figure out how have a gateway that goes forward only when the handful of tasks started complete.

Here is a few examples.

Process starts with a parameter of "Billing".

My complex gateway starts tasks 5, 6, 8, 10, 11, & 12.

Those tasks finish.  Meeting at some kind of end gateway.  Gateway somehow knows i want to proceed and the flow goes to the end node.(this is the part i need help with)

Process starts with a parameter of "QA".

My complex gateway starts tasks 4, 5.

Those tasks finish.  Meeting at some kind of end gateway.  Gateway somehow knows i want to proceed and the flow goes to the end node.

How do I make a gateway to deal with these incoming flows?  AND gates would wait for all 15 every time, complex doesn't work because the paths that need to complete are different sometimes.

I was thinking of a counter variable, but dont see a way to refrain from proceeding based on a variable.

At the moment I am pondering using a 5 min waiting loop, as this lets me direct based on a task  counter i could keep track of.

I  summary I would like some feedback on other ways to accomplish my goal of reconnecting these 1 to n flows and proceeding to my end node intelligently.

Thanks

FWIW, whenever I need to approach something like this, I usually defer away from complex gateways and use a more manageable design pattern like this prototype, wherein *all* paths are launched and non-needed ones are simply skipped over.  As far as I can tell, this circumvents the various pitfalls you mentioned pretty nicely, and even though it's slightly more costly in terms of nodes used, it's much more manageable and comprehensible.

Thanks. I think this fits my issue perfect without needing too many changes too.


For me the path 1 2 and 3 subprocesses are all the same process outfitted with different parameters, so i can probably cut down on nodes by including the not needed path inside the process and taking the not needed path within  based on a parameter.
