Currently I am working on 17.2 and created a process report in my site and trying to open portal tasks from a!processtasklink() function in a grid field.But every time I open the task it shows me error: The task has been deleted or completed by another user. But the portal task is still in active state and I am able to access it from /designer.
Do we have any other approach through which we can access portal tasks rather tempo tasks while clicking on task link in grid field?

You'll need to use a!safeLink() rather than task link. You can use the following expression to construct the uri:
concat( "http://yousite.com/suite/apps#app=system.tasks&nav=active;%2Fsuite%2Fprocess%2FgetTaskDetails.do%3FtaskId%3D", ri!taskId, "%26appian_environment%3Dapps" )
