Which client requirement aligns with using a custom BSO plan type along with or in place of the Workforce module?

The pre-built Workforce module uses a BSO cube (OEPWFP) with a fixed structure and dense/sparse configuration. If a client's data is very sparse across the module's dimensions, it can lead to a large number of very large data blocks, causing slow aggregations and calculations. A custom BSO plan type allows an architect to design the cube specifically for the client's data set, for example, by changing which dimensions are dense versus sparse. This custom design can significantly optimize performance by reducing block size and improving calculation efficiency, making it a valid reason to choose a custom solution.

A. The client would like to plan salary by Position: Planning by Position is a standard feature of the Workforce module.
B. The client requires more than three custom dimensions: While needing more than the two allowed custom dimensions is a valid reason, option E presents a more fundamental architectural and performance-based rationale.
C. The Operations department requires a more granular level of detail...: Varying levels of detail within a dimension are handled by standard hierarchies and do not require a custom plan type.
D. The client has 10 dimensions in the application...: The total number of dimensions in the application is not the direct driver; the specific dimensional requirements for workforce planning are what matter.

Oracle Cloud EPM, Designing with Calculation Manager for Oracle Enterprise Performance Management Cloud, EPM-CM, "Designing Business Rules, Rulesets, and Templates," Section: "Performance Considerations for Business Rules." This guide discusses how cube design, particularly dense/sparse settings, is critical for BSO performance, supporting the rationale in option E.
