Determining the Budget Object Element: With budget objects
If you have defined budget objects in the
budget structure, there are two ways of setting how availability control (AVC) works:Here it is assumed that every element defined as a budget object has received budget. If a budget object has not received budget, availability control checks the posting against a zero budget. The system does not search for a budget object higher in the hierarchy for which budget was allocated, but triggers the appropriate actions as you defined them.
This is the function delivered in the standard system.
To choose this function, make the appropriate setting in Funds Management Government Customizing. For more information, go to the Funds Management Government IMG and choose Budgeting and Availability Control
Determining the Budget Object Element: Procedure with Budget Objects

Starting from the funds center (secretary’s office) and commitment item (computer requirements) in the hierarchy, the AVC determines the first budget object in the following steps:
If you are working with the standard configuration, the AVC determines in the above example "Department 1/IT" as the budget object element. "Department 1/IT" is the lowest budget object.
If you have stipulate in Customizing that the AVC checks should be made in the first budget object with budget, the AVC searches up through the hierarchy until it finds the first budget object with budget. In the example above, the first budget object with budget is element "Department 1/Administrative expenses".
