1. SAP Help Portal - SAP Analytics Cloud, "Applying Linked Analysis in a Story":
This official documentation explains the core concept: "Linked analysis allows you to create interactions between charts... For example, you can have a filter in one chart apply to other charts in your story." It details how to configure interactions for page filters (Input Controls) to apply to "All Widgets on the Page" or "Only Selected Widgets". This directly addresses the scenario in the question.

2. SAP Help Portal - SAP SuccessFactors People Analytics, "Report Stories Administration Guide":
Chapter: "Designing a Story". This guide details the components of a story, including pages, widgets, and filters. It clarifies that the functionality for widget interaction and filtering is inherited from the underlying SAP Analytics Cloud platform, directing users to the relevant SAC documentation for features like Linked Analysis.

3. SAP Learning Hub - Course THR92 - SAP SuccessFactors People Analytics: Reporting and Story Design:
Unit: "Creating Stories". This courseware explicitly covers the creation of pages with multiple widgets and the use of page filters (Input Controls). The exercises and demonstrations show that to make an Input Control filter multiple charts and tables, the "Linked Analysis" panel must be used to define the scope of the filter's influence on the page's widgets.
