Can you please attache your workbook here..?
Are you looking for the field to be inside a pivot ?
If this is the case, then you need to go to the data source pane and add the field to the pivot, then it should show up in your data.
What connection used live or extract in your report.
If it is in extract, when publish to server we can allow for refresh and can add some refresh schedules. Server can update and show updated data.
If it is in live then just refresh server and get new data.
The problem I am having is that l can't see the new field's in the data source pane.
