What is one of the inputs to the Portfolio canvas?

The Portfolio canvas is a tool that helps define the value streams, solutions, customers, budgets, and other key aspects of a SAFe portfolio. One of the inputs to the Portfolio canvas is the Enterprise Strategy, which describes the vision, mission, goals, and objectives of the organization. The Enterprise Strategy provides the context and direction for the portfolio vision, which in turn guides the identification and prioritization of portfolio epics and value streams. The Enterprise Strategy also influences the allocation of lean budgets and the alignment of strategic themes across the portfolio. References: Portfolio Vision, Portfolio SAFe, What Sections Are Included In SAFe® Portfolio Canvas?, [Exam Study Guide: SP (6.0) - SAFe Practitioner]
