Chapter 5: Provide Drill-through Access • For a drill-through request to execute properly, a copy of the .iqd file must be replicated on the target Cognos Query server. The path must be the same relative to the folder in which Cognos Query is installed on the target server. • When performing a drill through, only the current dimension line settings are passed as filter parameters to the drill-through target. Unlike PowerPlay client, where the active cell is also passed with the dimension line setting, PowerPlay Web does not identify an active cell. Design Queries as Drill-through Targets The design criteria for a drill-through query are different from a cube creation query in the following ways: • Drill-through queries typically include many non-additive text properties that you would not include in a Transformer source query, such as Addresses and Phone Numbers. These columns are the objective of drilling through. • Drill-through queries should include links to other entities for further exploration. There is no reason to include links in .iqd files that you intend to use only for cube creation (not as drill-through queries). • Queries used as drill-through targets must be saved in a folder that all the drill-through users have access to. • Queries used as drill-through targets should contain the attributes used to define levels in the cube. Cognos Query can only filter on attributes included in the query. Save a Drill-through Target in Cognos Query PowerPlay Web requires an .iqd file to drill through to Cognos Query. To create the .iqd file, you must enable drill through for the report in Cognos Query and re-publish the report to Upfront. The .iqd file will be created. Steps 1. In your Web browser, open or create a Cognos Query report to which you want to drill through. 2. On the Cognos Query toolbar, click the Design button. 3. On the Advanced tab, click Properties. 4. Select the Enable Drill-Through Access check box. 5. Click the Run Query button. 6. On the Cognos Query toolbar, click the Save As button. 7. Follow the steps in the NewsItem wizard, and click Finish. The Cognos Query report reappears in your Web browser and the .iqd file is created on the computer where the Cognos Query server is installed. Note: After you create the .iqd file, you must use Transformer to specify the drill-through targets (.iqd files) for your measures or PowerCubes and update the cubes that you want to drill from (p. 62). Notes • Ensure that you use Cognos Query to create your .iqd files for drill through from PowerPlay Web to Cognos Query. Do not use .iqd files from Impromptu. Enable Drill Through to Cognos Query After you set up your .iqd drill-through targets and update your cubes, you can enable drill through in PowerPlay Enterprise - Server Administration. Steps 1. In PowerPlay Enterprise - Server Administration, click a cube, report, or folder. 2. From the Edit menu, click Properties, and then click the Settings tab. 3. In the Cognos Query box, click Enable. 66 Cognos PowerPlay (R)
Chapter 5: Provide Drill-through Access 4. In the Cognos Query Server box, select the URL for the Cognos Query gateway, such as http://servername/cognos/cgi-bin/cqcgi.exe Tip: You can also specify a Cognos Query Server group name in this field, such as Cognos Query Server Group 1. PowerPlay Enterprise Server resolves the location of the Cognos Query gateway from the Server Group definition in the configuration file. 5. To test that the drill through works, click Open with Browser on the Tools menu. Then drill through by clicking Drill Through and selecting the target report. Drill through to Cognos Query is now enabled. Drill Through to Impromptu Web Reports To set up drill through from PowerPlay Web to Impromptu Web Reports, you must perform the following tasks: • In Transformer, specify the drill-through targets (.imr files) for your measures or PowerCubes. You must then update all affected cubes (p. 62). • In PowerPlay Enterprise - Server Administration, enable drill through for each cube. Notes • Impromptu Web Reports requires users to log in to view a report. If your cubes use security, you can use the same authentication source if you want users to access Impromptu Web Reports without being prompted for a user ID and password. Impromptu Web Reports uses Access Manager to administer users and user class security, and a directory server to store the authentication information. If you have installed a ticket service, Web users will be prompted once per session for a user ID and password. If your cube is using the same authentication source, then users will not be prompted when drilling from the cube to an Impromptu Web Reports report. • Users need execute privileges for the drill-through target report to drill through to it from the PowerPlay cube or report. For more information about setting up drill-through reports, see the Cognos Web Portal User Guide. • If you design a cube based on an Impromptu query definition file (.iqd), the Impromptu report file (.imr) associated with the .iqd file is automatically added as a drill through target in Transformer. After you enable drill through to Impromptu Web Reports, the .imr file will also show up as a drill-through target. Enable Drill Through to Impromptu Web Reports After you set up your .imr drill-through targets, configure authentication, and update your cubes, you can enable drill through in PowerPlay Enterprise - Server Administration. Steps 1. In PowerPlay Enterprise - Server Administration, click a cube, report, or folder. 2. From the Edit menu, click Properties, and then click the Settings tab. 3. In the Impromptu Web Reports box (Drill Through), click Enable. 4. In the Impromptu Web Reports server box, select the URL of the Imrap.cgi file. For example, type http://server name/cognos/cgi-bin/imrap.cgi . Tip: You can also specify an IWR Server group name in this field, such as IWR Server Group 1. PowerPlay Enterprise Server resolves the location of the Impromptu Web Reports gateway file from the Server Group definition in the configuration file. 5. In the Impromptu Web Reports Drill Through Folder box, enter the name of the Upfront folder where the drill-through report is located. This folder name must match a top-level report folder in Upfront. Note: In Impromptu Web Reports, you can set up only one folder to contain drill-through targets for your PowerPlay Web cubes. However, more than one cube can drill through to this folder. Enterprise Server Guide 67
