Hi diptis,

The Start Process smart service is available as an expression function that can be executed inside a saveInto on a Interface Component or as part of a Web API.

So if you want to trigger a process model on click of a button or on an action performed on an Interface Component, subprocess wont help.

If you want to trigger a process model in a different Appian instance, you cannot use subprocess. Instead you have to use call a Web API which is in the target environment and in that Web API you need to trigger the process model using a!startProcess().

Hope this answers your question.

Sidhant Behura

Hi Dipti ,

While Using Start process smart service you can parametrise the inputs i.e. You can start any process model . But in Sub process you have to define it.

Also other important thing to consider is that sub process node starts the process in same engine as the parent process . so if this is called in MNI or loop a specific engine will load up which is a bad design . Start Process Smart service does that engine balancing efficiently .

Hi Dipti,

In my view :

start process smart service is asynchronous process so whenever want to trigger/start any process on certain condition and parent process not require to pause/wait to complete the other process. In this we can not inherit the security from the parent process.we can not take any data from child/other process back to parent/caller process model.

In the case of sub-process, we can make child process synchronous and apply chaining as well. Apart from this we can inherit the security from parent process to child process and take back some data from child process to parent process.

you can easily get the documentation in appian. Hope this may help you.

Abhay

Thanks Shiva
I have already read the documentation. I have a question that if we can start a process asynchronously using sub process then why there is a need of start process smart service ?

As start process smart service starts a process asynchronously which can be achieved by sub process also

Hi diptis ,
As far as I Know start process smart service can be used to complete multiple smart services and retrieve the results of the smart services from within an interface or web API.when using activity-chaining in conjunction with the Start Process smart service to ensure you use the smart service properly:
If a chained flow encounters an attended activity, the activity will be assigned to the user that the Start Process smart service was run as, but it will not open the associated form.
The "onError" parameter will only evaluate if the process fails to start. It will not evaluate if a node in the started process pauses by exception.
For more Info:docs.appian.com/.../Start_Process_Smart_Service.html

The Sub-Process Activity is used to launch sub-processes from within your parent process. It links the two published process models and allows you to transfer data between them.
Sub-processes can be run either synchronously (finishing before the parent process does) or asynchronously (completing at any time).

For more info:docs.appian.com/.../Sub-Process_Activity.html
