Hi Praveen - you'll have to elaborate somewhat. It's not clear what you're asking. What is your Use Case or the problem you're trying to solve?

Hi praveen kumar kaitha

You need to elaborate more on this, but if you want to get to the task from the process id then you can use the a!processTaskLink to get to the task from the process id where you can get the task id from getactivetaskidsforprocess()

If I understood you query correctly, you want to re-initiate/start a process Instance (but not the process model) by using the process instance Id because you might have some data in it's process variables and wanted to continue with the same.

If so, then it would be worth to have a look on Process Management Services available in App-Market. It has Start All Nodes Smart Service, which can be used to achieve your requirement, if i understood your requirement correctly.

In order to use this, you will need to pass Node UUID and the Process Ids.

Also, I would like to understand, why do you want to execute an already executed process instance once again?
