Retreive process values from Asynchronous sub process.

You can use send message and receive message events.

Hi Rakesh Singh,
I have a few doubts in this design approach,
As you aware that the parent process continues with its flow as soon as the Asynchronous sub process started.
What happens if the parent process Ends before the sub process ends?
You can pass the variables as reference but remember you should not pass the CDT's as reference.
If your design is insisting to go with Asynchronous sub process you can persist the details in DB and in parent process you can pull
them from DB.

Why cannot you try with Synchronous sub process?

Hello Rakesh,

Appian gives you an option to check the same , go to Configure Sub process Tab-->Other there option has been given
1.Confirmation URL in this field you can give the Intuitive URLs (such as /page/0) can only be used when submitting tasks within the Application Designer environment.
2.Keeping a Copy of a Form.

You can refer the below page and do let me know if it helps, we can discuss this more precisely.

Hi,

You can pass a variable say "subProcessStatus" as "pass as reference" in the Async sub process and just before the end event in the subprocess you can put a script task which would update the status of subProcessStatus variable as "complete".

In the parent process model you can configure rule event which will run only when the subProcessStatus is complete.

Thanks,
Nitesh

The parent process waits in the last node before completion to check that the async. sub process is completed. If I follow the DB approach how to capture the process completion flag?
Thanks,
Rakesh

Hi Ashwani,

But isn't it limited to the UI task/web page, what if I have additional steps after submitting the UI task? Also how will we capture when the task is completed.

Thanks,
Rakesh

Hi Rakesh as mentioned above "You can pass the variables as reference but remember you should not pass the CDT's as reference."
You can go with this approach and NiteshT already mentioned the good way, Please use that.

Thanks everyone for your valuable suggestions!!

Rakesh

Hi Rakesh,

Pass by reference will be a good approach for this situations untill unless u don't want to use the old PV! Value in the main process.
