Sub-Templates, Style Templates & Reusability
Explain how sub-templates and style templates promote reuse and consistency across many BI Publisher report layouts.
As a BI Publisher deployment grows to dozens or hundreds of reports, copy-pasting the same header, footer, and formatting logic into every single RTF template becomes an unmaintainable liability — a company logo update or a legal disclaimer change would otherwise require touching every report individually. Interviewers raise this topic to see whether a candidate thinks about template maintainability at scale, not just building one report in isolation.
It's like a company using a shared letterhead template for every department's correspondence instead of each department designing and hand-typing their own header from scratch — update the letterhead once, and every future letter from every department automatically uses the new version.
