Purpose
This process involves assigning budgets to the budget structure elements you have created.
You take a budget hierarchy, which you defined in the process
Definition of Budget Hierarchy, and assign the appropriate budgets (either monetary or full-time equivalent) to the individual budget structure elements contained in this hierarchy. In the case of FTE budgets, assigning budgets involves assigning the full-time equivalents, and also classifying the budget (i.e. assigning the appropriate pay scale characteristics).Budget assignment provides a basis for executing the budget (e.g. for financing persons or positions).
Prerequisites
You must have made the following Customizing settings for HR Funds and Position Management:

The monetary pay scale classification (default value amount) stored for FTE budgets is always the average pay of the pay scale group in question. A person’s actual pay is not used for classifying budgets.
You must also have defined a budget hierarchy (i.e. created individual budget structure elements), and the overall budget must have the budget status Proposed or Being revised.

If you create a new overall budget, or carry forward an existing budget, it is automatically given the status Proposed.
Process Flow
The top-down method allows you to display the budget still available, and to allocate this budget to lower-level budget structure elements.
In the bottom-up method, the budgets at the lowest level of the budget hierarchy are processed first. The available budget for the higher-level budget structure element is flagged as Exceeded and can be assigned accordingly.
A combination of both methods is also possible.
The following budget assignment scenarios are possible:
In all cases, the SAP System summarizes the budgets assigned at the various levels of the budget hierarchy. Any FTEs are converted into monetary amounts.
Result
You have assigned budgets to your budget structure elements. For information and monitoring purposes, you can use the
Display: Overall Budget function to display and print out your overall budget and the individual budgets in it. You can also start a consistency check.Once the budget status has been changed, you can start executing the overall budget (i.e. financing persons or positions with the budgets assigned to the budget structure elements).
