Hello,

I want to accomplish a simple thing.

A workflow is startet, and then split by a "inclusive data based" gateway. Imagine all flows (e.g. 3) are activated.

Each flow updates a global variable with additional data.

Right now - I think - the result is not determined. It looks like that the result is overwritten sometimes, sometimes not. If I execute the workflow several times, different results appear.

I designed the workflow in a consecutive way (one task after the other), and the workflow was fine.. but not optimal.

So my question: if the tasks are activated in parallel, how do I synchronize between the tasks that only ONE task accesses the global var at the same time?

Or is the only way to append the second task after the first and forgetting about executing them in parallel?

thanks
