Answer 1

Master-Detail Report from Two Separate Lists

A master detail relationship to deliver information that would otherwise require two or more reports. For example, you can combine a list with a chart. The list can contain product lines and the chart can show details for each product line.

Master detail relationships must appear in nested frames to produce the correct results. You can create a master detail relationship in two ways:

• Use a parent frame for the master query and a nested frame for the detail query.
• Associate a report page with the master query and use a data container, such as a list or crosstab, for the detail query.

You cannot display parent data in the child frame or child data in the parent frame. Also, you cannot perform calculations across master detail queries.

You can use a master detail relationship to show data from separate data sources in a single report. However, the data sources must be contained in the same package.

If you are working with an SAP BW data source, you cannot use a data item from the master query that contains non-ASCII values.

To create a master detail relationship using queries that reference two different dimensional data sources, you must first link the members by aliasing the levels that contain the members.

Steps

1. To use a parent frame for the master query and a nested frame for the detail query:
   • In the Insertable Objects pane, on the Toolbox tab , drag a List, Repeater Table, or Repeater to the report.
   • Add a second data container to the object you inserted.

You can insert a list, crosstab, chart, repeater table, or repeater into a list. You can add a list to a repeater table or repeater.

1. • Add data items to both data containers.
2. To associate a report page with the master query and use a data container for the detail query:
   • Click anywhere in the report page.
   • In the Properties pane, click the select ancestor button and click Page.
   • Set the Query property.
   • In the Insertable Objects pane, on the Toolbox tab, drag a data container to the report.
3. To link a data item in the master query to a parameter in the detail query instead of to another data item, create the parameter in the detail query.

Use parameters to filter values at a lower level in the detail query.

3. • Pause the pointer over the query explorer button and click the detail query.
   • In the Insertable Objects pane, on the Toolbox tab, drag the Filter object to the Detail Filters box.
   • In the Expression Definition box, create the parameter .
4. Pause the pointer over the page explorer button and click the report page.
5. Click anywhere in the report page.
6. In the Properties pane, click the select ancestor button and click Page.
7. Click the data container containing the details.
8. From the Data menu, click Master Detail Relationships.
9. Click New Link.
10. In the Master box, click the data item that will provide the primary information.
11. To link the master query to a data item, in the Detail box, click the data item that will provide the detailed information.
12. To link the master query to a parameter, in the Parameters box, click the parameter that will provide the detailed information.

Tip: To delete a link, select the link and press the Delete key.

13. If your detail query object is a chart, you can disconnect a chart title from the master query.
    • Click the chart title, and then, from the Data menu, click Master Detail Relationships.
    • Clear the Use the master detail relationships from the chart check box.
14. If your master detail relationship includes a chart as the detail and you are using automatic axis ranges, you can set the same axis range for all the detail charts:
    • Select the axis.
    • In the Properties pane, under General, double-click the Axis Range property.
    • Under Maximum and Minimum, click Automatic.

The master detail report option is only available with automatic axis ranges.

• Under Master detail reports, select the Same range for all instances of chart check box.

For more information about axis ranges, see Change the Axis Scale of a Current Default Chart.

Tip: To avoid seeing the same data item twice in the report, click the data item in the data container driven by the detail query and click the cut button. This removes the item from the report display but keeps it in the query.

Link Members from Two Data Sources

If you create a master detail relationship using queries that reference two different dimensional data sources, you may need to create a relationship between levels with the same member captions but different Member Unique Names (MUNs). For more information about MUNs, see Recommendation - Use Member Unique Name (MUN) Aliases.

For example, you may want to link the Americas member in the Sales territory level in the Great Outdoors cube with Americas in the GO Subsidiary level in the Great Outdoors Finance cube. To create the relationship, you must alias the levels that contain the members to link.

Steps

1. In the parent frame or the report page, double-click the level that contains the member that will provide the primary information.

The Data Item Expression dialog box appears.

2. In the Expression Definition box, use the expression in the following function:

caption ( expression )

For example, caption ( [great_outdoors_company].[Sales Territory].[Sales Territory].[Sales territory] )

3. Repeat steps 1 to 2 for the level in the data container that contains the details.

A caption alias is created for each level. You can now use the caption alias for each level to create a master detail relationship using member captions, which are the same, instead of MUNs, which are different.

You can now create the master detail relationship between the two levels.

Master Detail or Burst Reports with Charts or Crosstabs May Result in Denial of Service

When running a master detail or burst report that includes a chart or crosstab, disk space exhaustion may cause the report or other requests to fail. A large set of burst keys or master rows may produce one or more charts per detail, resulting in many master detail executions. This may cause the temp folder to accumulate many gigabytes of temporary files containing data required for successful chart rendering.

To avoid this issue, we recommend that you test large master detail or burst reports that include charts or crosstabs to determine the potential peak disk requirements for the report.

Configuring the Interactive Dashboard

This secured function controls access to the New > Dashboard and New > Story functions. Users require Execute permissions for the Dashboard capability both to create or view dashboards and stories.

Interaction Point Performance - Shows the number of offers accepted per interaction point over a seven day period.

This dashboard report is defined to point to the interactive channel with the ID of 1. To create additional versions of this report (to report on additional interactive channels) or to change the ID of the interactive channel that this report points to, see Configuring the Interaction Point Performance dashboard portlet.

• Configuring the Interaction Point Performance dashboard portlet
  Interact has one IBM Cognos dashboard report: Interaction Point Summary. Because dashboard reports do not prompt users for query parameters, the channel ID of the interactive channel in the Interaction Point Performance report is a static value. By default, the channel ID for this report is set to 1. If the channel ID is not correct for your implementation, you can customize the report and change the channel ID in the report's filter expression.
