When you want a performance review template with only anOverall section, the correct configuration isPrompt for Overall Rating.

This option requires the manager to provide a single overall rating without averaging or weighting items.

Other options:

Manual Entry→ applies to ratings on items, not a single overall section.

Calculated Ratings with No Overrides→ automatically calculates from section ratings (not desired here).

Calculated Ratings with Overrides→ allows calculation plus manual override, but still requires sections/items.
