Viewing large amounts of data in Personas

Hi All,

We have used SAP Screen Personas 1.0 to cater to a specific Dashboard requirement for End Users. Many of the buttons on the Dashboard involve List Transactions. When executing these transactions for getting a large number of data (say around 4 to 5 lacs of data), the page greys-out for a while and then gives us the following message:

“ The session has timed out – Please log in again.”

Would like to know if this is a limitation of Personas, or some kind of setting needs to be changed.

Kindly advise if anyone has faced the same, and what is the resolution.
