Overview
This course is designed to guide report authors in building on their expertise with IBM Cognos Analytics by applying dimensional techniques to reports. Through interactive demonstrations and exercises, participants will learn how to author reports that navigate and manipulate dimensional data structures using the specific dimensional functions and features available in IBM Cognos Analytics.
Audience
Report authors working with dimensional data sources.
Prerequisites
• IBM Cognos Analytics: Author Reports Fundamentals (v11.0)• Knowledge of your business requirements• Knowledge of dimensional data
Objective
• Compare dimensional and relational data sources • Understand dimensional concepts and reporting styles • Create reports using dimensional data items such as members, levels, and hierarchies • Focus reports using dimensional techniques such as edge filters, slicers, and filter functions • Navigate dimensional data structures using functions to find related members or comparison time periods • Create sophisticated measure calculations • Understand totals and aggregation • Analyze reports with drill-up and drill-down techniques • Configure advanced drilling behavior to support complex calculations and dashboard reports • Set up drill-through access from one data source to another
