Using Excel with Cognos TM1 and Cognos BI
Cognos Analysis For Excel (CAFE) is a popular way for business and financial analysts to combine enterprise information with local data in an Excel spreadsheet that can be refreshed as server information changes. In this webinar recording, we look at the capabilities of CAFE, compare them when using the tool with TM1 versus Cognos BI as a source and share useful tips and caveats along the way.
Providing demos of concepts, we cover the following topics:
- Differences between using CAFE with TM1 and Cognos BI
- When and why to consider using CAFE
- Useful techniques and common pitfalls
If you'd like to learn more, you may be interested in taking our Cognos Analysis for Excel training course. You will learn how to combine queries of Cognos data with Excel features to create complex, presentation quality reports. It also covers customization options and sharing of CAFE content.

What is CAFE?
- Excel add-in (IBM Cognos tab/ribbon)
- Provides analytical and report authoring capabilities against Cognos BI packages and TM1 cubes
- Evolving as the successor to TM1 Perspectives, the legacy add-in for TM1 forms and reports
- Productivity tool to streamline report writing tasks
Why use CAFE?
- Excel is the most widely used reporting tool with estimates of nearly 1 billion users. Many reports will be done in Excel; CAFE can make the task more productive, reliable and accurate.
- Leveraging Excel skills can broaden authoring and self-service capabilities within the organization.
- Enables IT/BI groups to focus on high priority, high impact projects and delegate some report writing to business users.
- Best of both worlds: Excel ease-of-use, cell-based calculations and formatting, charting, print precision combined with refreshable links to governed, system of record data.

- Develop guidelines within your organization for when to use CAFE versus Cognos BI for report development
- Leverage CAFE as tool for business users to prototype and provide specifications for BI report requests
- Do not use CAFE to download large data sets, there are more efficient ways to move large amounts of data to the desktop
