Yes - Appian's chaining limit is 50 by default. It counts every flow line (and some you aren't expecting), so if you think there are 45 nodes, you're probably exceeding the 50 by quite a bit.

It's really an extremely bad idea to have a situation where you need to exceed (or even, really, get close to) that number - there are alternate design approaches you should consider in this case, like off-shifting some of the subprocess functionality into asynchronous subprocess calls, etc.

The only thing I can think of is there is a timeout happening.

To update my original PM configuration: if there are many sub-processes (total, about 45 nodes) in between the first user task and the second group A user task, is there a timeout with activity chaining?

I just tried it in my own simple example and it seems to work fine for me - the user who completes the first task chains straight into the subsequent chained task (even though it's assigned to a group).

What exactly is happening when you try?

Here is the configuration. When I took away the Group B user input task, it still did not directly chain from the Group A user task to the other Group A user task.

Please post a screenshot of your process model configuration. If I'm assuming correctly that you're saying you want the "group A" task after the AMD gate to be chained into directly by the user who completed the prior step, this should be fine as long as your configuration is proper.

Hi,

If you are assigning to the different groups better you can have to use XOR gateway. Visual approach is better reach to give the proper answer.
