Report builder not showing updated data

Hi
One answer

I will assume that you are using the right data source for your project (i.e. Configuration Management is NOT enabled so the Data Warehouse is still applicable).

If you know when the DCC job stopped working, then you can set 'Delta load since date...' option in 'Delta Load Configuration'. DCC job will run faster with less impact on performance than full load.

This is the thing, we are not having any failed jobs as its just missing only for very few work items while rest of them is showing pretty fine. I will try to see with the team if they can run Full load as suggested by Daniel or Delta load since date if we find some exact date ( which is challenging to know )
