Use
You can use this function to increase or decrease the budgets of budget structure elements defined in the overall budget during a financial year.

An additional budget for the budget structure element Salaries for Civil Servants means that the original budget for this budget structure element is increased by USD 100,000. You use a budget update to assign these additional funds to the budget of the budget structure element Salaries for Civil Servants.

Budget updates are entirely user-definable (returns/supplements, descriptions). You make your own customer-specific entries for this in Customizing.
Budget updates are different to the changes made to the original budget during the Budget Allocation process because the overall budget now has the budget status Released.
Prerequisites
You must have made the appropriate settings in the following Customizing steps: Overall Budget ®
Budget Updates ® Define Budget Updates and Assign Budget Updates to Specific Budget Structure Element Types.Features
A distinction is drawn between supplements (increases) and returns (decreases).
You specify a supplement or return either as a monetary amount or as full-time equivalents (depending on the budget structure element type) for a specific validity period.
The system calculates the total amount of the budget update on the basis of the number of full-time equivalents specified and the validity period. When you create a return, the active availability check checks whether the budget of the budget structure element is actually available.
