sdc/duplicate-declaration ​

error Reports a name declared more than once on one item or on the root.

What it checks ​

Looks for two declarations of the same name on the same item, or on the Questionnaire root: variables, other named expressions such as an itemPopulationContext, launchContexts and extractAllocateIds, in any combination. The later declaration is reported, with the first as a related location.

Example ​

The name %weight is declared more than once on item "BMI" (bmi), so it is unclear which value expressions that use it get.
