Chapter 5: Provide Drill-through Access Note: This creates the drill through filter expressions that you will need for creating the Cognos ReportNet target report. 4. Click the Drill Through button on the toolbar. The Assist Drill Through page appears. The PowerPlay cube metadata section lists the items available for drill through, and the filter expressions section lists the parameterized equivalent that you will build into the target report. 5. Copy the first item you require from the filter expression section to the clipboard, using CTRL+C. 6. Leave the Assist Drill Through page open as you create the target report. Create the Target Report In Cognos Report Studio, you create the target report to which this cube will drill through. Steps 1. Open Cognos Report Studio and click New. 2. Create a new report by adding query items and any other objects. 3. From the Data menu, click Filters. 4. Click the Add button, and in the Tabular Model Filter dialog box, create the parameterized filter in the Expression Definition box. Tip: Use CTRL+V to paste the filter expression you copied to the clipboard when you selected filters for the target report. Return to the Assist Drill Through page and copy the corresponding Parameter values entry. For example, if the value of the filter expression in the Assist Drill Through page is [Country]=?Country? and the corresponding Parameter values entry is United States, you will copy and paste the values into the Expression Definition box to get [Country]=?United States? 5. Click OK. 6. In the Usage box, click Optional. Tip: If you do not make the filter optional, a prompt page will appear each time a user drills through to the report. You may find it useful to leave the usage set to Required permanently, to ensure that users do not retrieve large datasets, or to Disabled temporarily, during the development of the report. 7. Click Save to save the report. Note: The report name and case format (uppercase, lowercase or mixed case) must match the target report name that you built into your model in Transformer (or in PowerPlay Connect for other OLAP servers). For more information, see "Set Up Drill-through Targets in Transformer" (p. 62). For more information about creating reports and filters, see the Cognos Report Studio User Guide. Disable Cognos ReportNet or Cognos 8 Drill Through Assistance After you have created your target reports, tested the drill through functionality, and before deployment to production users, you will need to disable the Assist Drill Through page. By disabling the Assist Drill Through page, users drill through directly to the target reports. Steps 1. In PowerPlay Enterprise - Server Administration, click the cube. 2. From the Edit menu, click Properties. 3. In the Settings tab, expand the Drill Through folder. 4. In the Cognos ReportNet/Cognos 8 Assistance box, click Disabled. 5. Click OK. 70 Cognos PowerPlay (R)
Chapter 6: Audit Server Activity Use auditing to assess server, cube, and report activity and system performance of PowerPlay Enterprise servers. This information helps you make decisions both before and after you deploy cubes and reports to the Web, that can improve system performance. For example, if you know that only half of the 20 cubes published to your PowerPlay Enterprise server are accessed by users, you can stop publishing and maintaining the unused cubes. PowerPlay Enterprise Server auditing gathers data into text files. You can use the PPESAuditFileProcessor Utility (p. 73) to load the auditing details into a database. For auditing information to be logged, it must be enabled at both the server and cube or report levels. You can audit at the summary or detail level. The following table lists what is logged for each combination of settings. Cubes and Reports Servers None Summary Detail None Nothing logged. Server startup and shutdown messages. Details on requests made to the server from PowerPlay Web and by PowerPlay Enterprise - Server Administration. Summary Nothing logged. Server startup and shutdown messages. Server requests made to cubes and reports from all PowerPlay clients. Details on requests made to the server from PowerPlay Web and by PowerPlay Enterprise - Server Administration. Requests made to cubes and reports. Detail Nothing logged. Server startup and shutdown messages. Measures and dimensions accessed from PowerPlay Web. Details on requests made to the server from PowerPlay Web and by PowerPlay Enterprise - Server Administration. Associations between user requests and logged activities. Measures and dimensions accessed. Follow this process to set up auditing: ❑ Enable auditing. ❑ Set up an audit database using one of the following methods: • by restoring the Microsoft SQL Server sample database if you want to run the reports on the sample data. Note: To restore the sample database, you must install the samples. The samples are included with the default installation. Enterprise Server Guide 71
