A project and its WBS elements go through different stages, or statuses. The status determines whether you can use certain business transactions or not. You can exclude a WBS element with budget and the lower-level account assignment elements from availability control. You do this by activating a user status for the controlling element, for which the availability control business transaction is not allowed.

If a WBS element has this status, then the assigned funds are not included in the availability control, in other words, no action is triggered. However, the assigned values are still updated on the controlling element.
