If the Budget column is reporting a Nil value, check the Report Criteria, if your report is in a Bundle, click on CONFIGURE on the right to check:
Is the Business Unit Selection correct, should this be for the Organisation or a Business Unit Tree?
Is the Budget version selected in the report correct?
Check the date range selected is correct for your reporting period
To change any of the above settings, click the drop down, update and then REFRESH the screen, if this resolves the issue, you can click SAVE to update the report in the Bundle
If you still have zero values in the Budget Column, and you are reporting at the Organisation level:
Go to the Budget Grid screen
Select the Organisation and Budget version the report is referring to in the grey Banner
Click CONSOLIDATE at the top of the Budget grid
Choose the area of the business used to consolidate to the overall organisation figures, e.g. Projects / Departments etc
Confirm with CHANGE SETTING
Return to the Report and re-run.
