What exactly is it you want to do with the data from the report definition?    

Do you want to display it?  If so then you can source repeat grids from Report Definitions.

If you want the data available for reference then you could source a Data Page from the Report Definition.

If you could provide some more detail about what you want to achieve that would be useful.

Additionaly, which Pega version are you using? 

Hi sarithaa9@saru,

I have uploaded 3 screenshots. It shows how a Report Definition is used by a Repeat Grid in a Section, how a Section is called by a Flow Action and finally how a Flow Action is invoked by a Flow. 

Thanks,

Susan
