Ignoring a budget will remove the budgets impact from the cash flow. When removing a budget, this can be done on a budget occurrence level or budget as a whole level.
To ignore a single budget occurrence, first click into the cell where the budget exists and then click into the budget itself.
From here, click the eye symbol against the relevant budget and this will ignore the budget from the cash flow. Be sure to save this change so it takes effect. Clicking the eye symbol again will include the budget back into the cash flow.
If the budget is to be fully removed, rather than just excluded, select the red x symbol and this will delete that occurrence of the budget.
If the full budget is to be ignored or deleted, this can be access from the options within the 'Batch update'.
