Within SAP, a cost object is considered either a cost center or WBS element. Cost centers are used to track income and expenses for state-aided (non-revolving and revolving), auxiliary and other types of funds (endowments.) WBS elements are used to track income and expenses for grants, loans and plant funds. The new cost centers and WBS elements are entirely numeric. There is visual recognition built into the numbering structures to identify the campus, fund type, sub-program and department.
Following is the SAP cost object structure for a cost center and WBS element.
