Thanks for posting on PSC,
If I am not wrong, you want to pass parameters from section to a data page which is source with a report definition? And these passed parameters to be used as filter conditions in report definition?
I think the above post is little jumbled, correct me if my understanding is wrong and provide a detailed description of your business requirements with screenshots for better understanding.
Otherwise, you can refer this article to implement how to pass parameters to a data page. Link- https://pdn.pega.com/use-parameters-when-referencing-data-page-get-right-data
Hope it helps, kindly notify if it does by marking this post as answered for larger Pega audience and tracking purposes.
