The file has the name you gave to the data source, with .oqy—for OLAP Query—as the extension, and is registered with the Microsoft Excel OLAP Query file type. Double-clicking the OLAP query data source file starts Excel and creates a new PivotTable report based on that data source. 6. The Choose Data Source dialog box appears again. Click OK. 7. Step 2 of the PivotTable Wizard appears again. Click Next and then click Finish. A skeletal PivotTable report appears on the worksheet, along with a PivotTable toolbar that displays all the dimensions and measures in the cube. Note vi Module 13: Using Excel as an OLAP Client BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Other Activities Difficult Questions Below are difficult questions that students may ask you during the delivery of this module and answers to the questions. These materials delve into subjects that are within the scope of the module but are not specifically addressed in the content of the student notes. 1. Can you export an Office PivotList back to an Excel PivotTable report? Yes. To do so, click the Export To Excel toolbar button. Interestingly, if you show only selected levels in a PivotTable list and then export that list to Excel, the resulting PivotTable report will include only the selected levels. 2. Can you update the subtotal labels in a PivotTable so that they match the total of only the visible cells? Unfortunately, you cannot make the subtotals match the total of only visible cells. However, you can turn off subtotals for dimensions. 3. What happens if the PivotTable toolbar becomes small and does not include all the dimensions and measures? Click the PivotTable in the worksheet. The toolbar should return to its original state. 4. How do you retrieve the PivotTable toolbar if you accidentally close it? Right-click the Excel toolbar, and click PivotTable from the list of possible toolbars. 5. Does an Office PivotList support events? If you write Microsoft Visual Basic ® code and are familiar with creating event handlers to react to the behavior of users, you might be interested to know that an Office PivotList supports events for numerous user actions. In contrast, an Excel PivotTable report does not have any events. Module 13: Using Excel as an OLAP Client vii BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Module Strategy Use the following strategy to present this module: ! Office 2000 OLAP Components Begin by defining the Office 2000 OLAP components—PivotTable Services, Excel 2000 PivotTables, Office Pivot Web control, and local cubes—and describe how each component is used to access OLAP data. ! Using Excel PivotTables In this section, you show how to create, manipulate, and format a PivotTable based on an OLAP cube. Integrate your lecture with a demonstration. First, show how to define the data source. Next, show how to use the PivotTable toolbar and how to drill down and pivot in a PivotTable. Describe how to use various methods that enhance PivotTable reports, such as filtering and refreshing. Finish the section by describing various formatting options for PivotTables. ! Using PivotCharts Explain that Excel 2000 creates PivotChart ® reports that are fully interactive and integrated with PivotTable reports. Emphasize that a PivotChart is always linked to a PivotTable. Describe the two methods of creating a PivotChart and integrate your lecture with a demonstration showing students how to create a PivotChart from an existing PivotTable report. Finish by describing some unique characteristics of PivotCharts. ! Working with Local Cubes Define local cubes as structurally complete OLAP cubes that reside on client computers. Compare and contrast local cubes and server-based cubes. Explain that you can create a local cube from either an OLAP source or a relational source. Combine your lecture with a demonstration showing how to create a local cube from an OLAP source. ! Creating OLAP Enabled-Web Pages Explain to students that Office 2000 makes it easy to create Web pages from Office documents. Describe and show how to create a Web page from a PivotTable report, combining the lecture and demonstration. Next, describe how to manipulate a PivotList—using the Field List, adding and removing items, and filtering and pivoting.

Lead-in In this module, you will learn about the OLAP components available in Office 2000. 2 Module 13: Using Excel as an OLAP Client BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Office 2000 OLAP Components ! PivotTable Service ! Excel 2000 PivotTables ! Office Pivot Web Control ! Local Cubes Excel 2000 PivotTables are the focus of this module. Other important OLAP features exist, however, in Office 2000. This module reviews the various OLAP components of Office 2000. PivotTable Service PivotTable Service (PTS) is the mandatory client component for querying Analysis Server. While PTS is a component of Analysis Services, it is also bundled with Office 2000. PTS places OLAP functionality on every Office 2000 desktop, regardless of whether users have access to an Analysis Server. PTS has no built-in user interface. It is an invisible component that provides OLAP functionality to Excel 2000, third-party applications, and custom applications. PTS provides the OLE DB for OLAP and Microsoft ActiveX ® Data Objects (Multidimensional) (ADO MD) object interface. Because PTS communicates with relational databases, PTS provides OLAP functionality for organizations that do not use Analysis Server. You do not need to install PTS on every client computer. To provide OLAP capability in a thin-client environment that does not require much memory usage on client computers, you can install PTS on another computer that acts as a middle tier and provides OLAP access for the client computers. Topic Objective To introduce the various Office 2000 OLAP components. Lead-in These are the Office 2000 OLAP components that are discussed in this module. Delivery Tips Briefly describe each of the components and define how they are used to access OLAP data. Except for PTS, do not go into detail, because each component is covered later in the module.
