This is the development of a reporting system for the zero base budget, using PowerBI
To extract the data, run a report from SAP tables COSP and COSS (that have the accounting costs by cost center and account).
Zero-based budgeting is one of the budget planning methodologies that is commonly known as OBZ, this tool requires managers to justify all of their budgeted expenses, rather than a more common approach of just requiring justification for incremental changes to the budget or actual results the previous year. Thus, a manager is theoretically assumed to have a zero expenditure baseline. OBZ is a plan made from scratch, with no background so it works, everything needs to be carefully budgeted and aligned.
In reality, a manager is assumed to have a minimum amount of funding for basic department operations, above which additional funding must be justified. The intention of the process is to continually focus the financing on key business objectives and to close or reduce any activity that is no longer related to those objectives.
The basic process flow under a zero-based budget is:
The concept of tiered expenses can also be used in reverse, where you outline the specific costs and capital investment that will be incurred if you add an additional service or function. Thus, management can make discrete determinations of the exact combination of incremental cost and service for its business. This process will usually result in at least a minimum service level, which establishes a cost base below which it is impossible for a company to go, along with several service gradations above the minimum.
