Hi @NagarjunaS16644648: This depends on the data access pattern. Please see details here.
If you need the snapshot of data (at that point of time) you will use copy from. When you need real time data always, you need to use Refer to data page.
Thanks.

Refer to Data Page - when we want the property to refer the data page every time it is getting used. Property will always have latest/sync data as Data Page.
This option ensures the data to be latest and sync with the DP. Data and loading of DataPage depends on the load management used.
Copy data from a Data Page : This will copy the data of the data page when it is referenced first time and will have the stale data until be clear the property explicitly.
This option only make DataPage to load once, and create a copy of it. Next time when property is referenced, it refer the copied data and do not hit DP again.
