What is the use of Budget Details in Position, is it for information purpose only?

Summary:

Navigation: My Client Group>Workforce Structure> Position>Create Position

In the Create/Edit Position we have a section called Budget details the following fields are present Budget Amount, Currency, Remaining Budget Amount Allocation, Cost Center and Funded from Existing Positions.

I would like to know if these field are related to other component of the system or is it for information purposes only.

I found a documentation on position budgeting however i could not proceed with the step below nor i am sure if this is indeed connected to my question.

I would appreciate if anyone could help me understand this section,
