This is a method of budgeting where all expenditures must be justified each period, rather than only explaining the amounts requested in excess of budget for the previous period.
You can create budget lines for ledger accounts without referring to current balances or the results of the previous period. For each line that you create in the Ledger budget form, you can select the budget model, the ledger account, the start of the period, and the currency. You also can enter an amount or you can enter a quantity and price to create an amount on the General tab.
To create budget lines for each budget year period for the ledger account, you can use the methods in the Allocation section. In the Method field, select Period to make the Quantity, Unit, and End date fields available. Or, you can select Key in the Method field to be able to select from the period allocation keys that you create in the form. You can create period allocation keys for each ledger account if necessary. For more information, see Period allocation key (form).
To verify that all the ledger accounts are represented in the ledger budget, you can create budget lines directly from each ledger account in the chart of accounts. To create budget lines, click Chart of accounts, select a ledger account, and click Ledger budget.
