we want to display a grid report with task ID as task link and business data associated with each task.but we are able to get task id separately using queryprocessanalytics ,

@suganyasrip Few questions here:
1. What is the category(such as Processes Per Process Model, Tasks Per Process Model, Tasks Per User etc.) of the Report?
2. What is "MyModel"? Have you mentioned it intentionally to hide implementation details from us or are you providing the process model object to contextProcessModels argument in the similar fashion?

Also please check for the presence of the errorMessage in the result(mentioned above by you) and it might be at last in the datasubset.

@sikhiI I used Task per Process Model to customize my report, My model i have changed intentionally.Am not getting error in in Error context .@navajithh Am able to see data in process report.

@suganyasrip, Could you plesae try creating a constant of type process model and map "My model" process model to this cons and then map it to the contextProcessModels property of a!quyeryprocessanalytics?

@suganyasrip Would you please be able to follow the link at https://forum.appian.com/suite/help/16.2/Task_Report_Tutorial.html and check if you are missing any of the steps? The only difference is you need to provide a process model constant to 'contextProcessModels' argument.

I hope that the value provided to report argument is a constant of type document and pointing to a valid Process Report and the value provided to 'contextProcessModels' argument is a constant of type Process Model.

i tried as navajithh mentioned , its working fine . Thank you all for helping me to resolve this issue.Thank you so much

@suganyasrip Cool, that's why I asked initially if you are intentionally representing the contextProcessModels argument in the text format.
