Hi John,

Thanks for posting the query.

You can now retrieve large data sets more efficiently with improved paging in data pages that are sourced from report definitions. Data page memory and performance is optimized because paging is done on the server instead of the client. You can set up server-side pagination for data pages with the following criteria:

• Structure - List
• Mode - Read-only
• Scope - Thread or Requestor
• Source - Report definition

For more details on this option, please refer to the articles:

Hi, Tried based on provided guide, still datapage gets all the data in the first call, it is not considered paging configured in report definition or repeating grid.

Agree with  @JohnPaulRaja,C  , It's not working as defined.  Have tried in Personal Edition 8.4 , but it seems to be retrieving all the records defined in report.

Can someone please provide clarification on this, We are dealing with large amount of data in our application and it would be great to have this functionality.

Appreciate a clarification on this.
