There are two reasons to rebuild budgets:
If you have edited a budget but the changes do not appear on the Budget Comparison Report.
If you import G/L budgets for a partial fiscal year; for example, if you import a budget for a quarter but not an entire year.
To rebuild budgets
Go to Admin > Toolbox > Rebuild Budgets.
Select a property and the date range you want to rebuild.
Click Rebuild Budget.
When Breeze has finished rebuilding the budget, a confirmation message appears.
