How to configure Gateway to show compound requirements as "covered" in the coverage analysis report

Technote (FAQ)


In IBM Rational Rhapsody Gateway Add-on (Gateway), how can you configure the default setting so that a compound requirement will be shown as "covered" in the coverage analysis report even if all of its sub-requirements are not satisfied?


The default rule used in Gateway to detect uncovered requirements is designed to treat a compound requirement as not-covered if all of its sub-requirements are not satisfied.

According to 'SysML specification v1.2', in order to make a compound requirement "covered", all of its sub-requirements have to be satisfied, and Gateway's default behavior match with the description.

"The default interpretation of a compound requirement, unless stated differently by the compound requirement itself, is that all its subrequirements must be satisfied for the compound requirement to be satisfied. Subrequirements can be accessed through the “nestedClassifier” property of a class. "
