To represent setup time as a graphical object in the Detailed Scheduling Planning Board, which action is necessary?

In the Detailed Scheduling Planning Board within SAP production planning, representing setup time as a graphical object allows users to visualize transitions between production tasks that require setup. The correct action to achieve this is to create and assign a new graphical object specifically designated for setup time. This graphical representation helps in distinguishing setup activities from production or processing activities, thus providing better clarity when planning and scheduling.

Creating the graphical object ensures that setup times are visually integrated into the planning board, allowing planners to see where setup activities impact production schedules. It helps in analyzing the impact of setups on overall efficiency and can assist in optimizing the production flow by clearly indicating when setup times will occur.

The other options do not directly address the need for a graphical representation. Running heuristics, assigning setup groups or keys, and creating a setup matrix focus on different aspects of production planning, such as optimizing setups or managing data. While these actions contribute to effective planning, they do not involve the necessary graphical representation that gives planners immediate insight into setup times on the planning board.
