report

The error is not about the report. It is about the context on which the report is being built. Like the user, groups, or any other thing that you used. 

a!queryProcessAnalytics(
  report: cons!SG_Exercise8,
  contextUsers:  {
    cons!MAKER_GROUP,
    cons!CHECKER_GROUP,
    cons!MANAGER_GROUP
  },
)

it looks like you passed in a list of groups for the parameter contextUsers - you should probably be passing that list into the parameter contextGroups, which is, of course, a different parameter.

yes I have tried with the context Group, it is giving me the only one group task assigned list that is manager group task lists ,but I want maker ,checker task lists as well,how will i get all these groups assigned tasks

a!queryProcessAnalytics(
  report: cons!SG_Exercise8,
  contextGroups:   {
    cons!MAKER_GROUP,
    cons!CHECKER_GROUP,
    cons!MANAGER_GROUP
  },
)

When run like this, the QPA call will return the report data evaluated against all 3 groups passed in.  I.E., the back-end data resulting from the call should map exactly 1:1 with what you're seeing in the visual Process Report editor.  If it still isn't doing that, then you might have a different issue with your configuration.

What is the nature of the data being returned by your QPA call here which makes you think it's only getting the results for one group?

Okay,how can I made changes in the report ? With the list of tasks assigned to those group users?

to confirm - when you edit the report object itself, what context does it take?

when I edit the report will get this and I have given report context as these groups, Because I need list of tasks assigned to these groups only.   

In that same area, when viewing the report in /design, does it show tasks for the Maker and Checker groups?

And what are the results you see for tasks, in the report editor, when it's set to those context groups?  Unless something else is wrong, like I said before, I'd expect to see the same list of tasks there in the report editor as well as resulting from your QPA call (assuming it's pointed at the exact same report and passing in the exact same list of groups for context).

No it is giving me the list of manager tasks only. It is not showing maker and checker group tasks.

So the process report itself shows all task as expected, but QPA does not?

Could it be that there are more tasks than the standard batch size is. Did you try to use a pagingInfo with a large batch size in the QPA call?

I agree with Stefan - please paste your entire QueryProcessAnalytics call here so we can see exactly what you're doing.  That is, including the "query" block including "pagingInfo".

If I am taking this correctly, this reply to my question (?) indicates the underlying report in /design does not show anything other than the Manager tasks, so there are no others in the report to pass up via QPA.

For which we have not confirmed there are any other of these tasks active in the system, for those other 2 groups?  

okay.
