What is the purpose of shared formulas in a planning system?

The purpose of shared formulas in a planning system is primarily to enable consistent and standardized calculations that can be utilized across different users and sheets in the system. Shared formulas allow teams to collaborate effectively by using the same underlying calculations, ensuring that everyone is working with the same data and logic.

When a formula is marked as shared, it can be easily referenced and modified in one central place. This means that if any updates are made to that shared formula, all instances of its use will reflect those changes automatically, which streamlines the planning process and helps maintain data integrity. This capability enhances collaboration and minimizes errors that could arise from inconsistent formulas being used by different team members.

The other options do not capture the primary function of shared formulas, as they focus on user-specific settings, override scenarios, or security measures, which are not the main objectives of using shared formulas in a planning environment.
