Hi,

I'm new to PM.

Grateful if I can be advised how nested subprocesses can be implemented. I.e. a task at level 1 calls a subprocess A at level 2. Then inside this subprocess A at level 2, there is a task calls another subprocess B at level 3. All these processing can be of synchronize type and return to the highest level master process before going ahead.

Thank you very much

cheers,
Karl

Karl, I played with this and found that ProcessMaker has a bug when using nested synchronous subprocesses. When returning from subprocess B to subprocess A, it cannot go directly to an end event in Subprocess A. Instead, it needs to go to a normal task.

Let's say this is your master process:

And this is your subprocess A:

And this is your subprocess B:

In subprocess A, you need a task before and after the subprocess B. If you don't have a task after the subprocess, then you will see the following error when returning from subprocess B to subprocess A:

The only way to get it to work without errors is to have tasks before and after each subprocess. I will file an internal bug report about this problem.

thank you very much for your effort and kind attention.

SubProcesses is very useful in handling complex systems.

It would be great if the operations of SubForms can be enhanced as well. Eg allowing SubForms as multiple tags of a Dynaform, allowing editing of subforms to deal with different conditions, etc.

You can file a bug report requesting this feature.

If you know a little programming, you can implement subforms with conditions for the Dynaform step and PMFRedirectToStep(). Here is an example:

Thank you for your advice. I'll study the method you advised.
