This is likely to be caused by an irregularity in either the Revision selected, or the data held within it when extracting via he Nominal Get Budget enquiry window.
Access Financials will show the selected budget, but if that value is blank then the previous revision will be shown, or the actual, if no previous is available.
It is not possible to upload a 0 budget via inXL, but it can be done using the AOI budget template
In the INXL Get Budget report, column D is usually titled Latest Rev Nbr (Default).
This is not the revision number chosen when running the report, but instead actually states and confirms what the latest revision number is for the budgets of the nominal accounts.
If the latest revision number is different to what you selected for running the report, you would have to run Get Budget again to select to view the latest revision number that column D specified for the nominal accounts.
This will then pull back and reflect the same budget figures you can see in Dimensions.
When the budgets are updated, the latest revision number will increase, making the previous revision a forecast.
Note: It is best practice to keep all of your nominal accounts in the same revision, and when updating any using AOI, you should update all the accounts to the latest revision.
Ensure to also re-instate any figures that are not going to change, because leaving them blank will then show the budget as 0, and not copy the figures over from the previous revision.
