Attribute value URL appears in reports

Impossible to answer this from the information provided. JRS depends on what tracked resources a data provider exposes through their TRS. If there is an enumeration value referenced by a property, and that enumeration value has not been indxed by LQE, then Report Builder can only show the URI of that enumeration value as referenced by the property. Note that, in DOORS Next, the type system is versioned. Removing enumeration values from an attribute data type will remove it from a specific version of that attribute data type in a specific stream, but that value will continue exist in other configurations and in prior versions of that attribute data type. If you want to progress this further, I suggest you open a case with IBM Rational technical support.
