Definition of Budget Hierarchy 
Purpose
This process describes how you define and maintain a budget hierarchy for an overall budget that you want to set up in HR Funds and Position Management.
The budget hierarchy is used to determine what the individual
budget structure elements are and to show how they are linked hierarchically. Defining a budget hierarchy is the first step in setting up an overall budget.Budgets (either monetary or FTE budgets) are assigned to the budget structure elements in the budget hierarchy. These budgets can then be used for the purposes of financing persons or positions.
The budget of a budget structure element is the funding that can be used for financing the persons or positions in an overall budget.

In this process, you define the basic structure of the overall budget. This process does not, however, involve assigning budgets to budget structure elements.
