Which of the following is NOT one of the three methods for planning costs?

The correct choice indicates that budget realization planning is not one of the traditional methods for planning costs in SAP. The primary methods for planning costs typically include manual, structure-oriented planning, easy cost planning, and automatic cost planning.

Manual, structure-oriented planning involves outlining costs according to a predefined structure, enabling a more detailed and methodical approach. Easy cost planning allows for quicker estimations by simplifying the input process, while automatic cost planning uses predefined algorithms and data for efficient cost estimation, facilitating an automated approach to budget management.

In contrast, budget realization planning focuses on tracking and monitoring how the planned budget is being implemented and realized, making it an aspect of budget management rather than a method used for planning costs upfront. Therefore, this distinction reinforces why budget realization planning does not fit into the traditional category of cost planning methods.
