Bi Viewer Reporting- Getting Errors

Hi Team

i have created a Bi Viewer report by fetching the People Planning Plan Data tab using SQL Data Adaptor and getting this error while opening the report from Workflow.

My assumption is this error is popping up because of large dataset in the people planning data tab, as this is opening with lesser amount of data records, is there any way to make it work or to increase the no of rows for a bi- Viewer report?
