C1000-065 Exam Dumps : IBM Cognos Analytics Developer V11.1.x

To address the user’s requirement to see only newer entries based on the 'Order Date' column while keeping historical data available in IBM Cognos Analytics V11.1.x, you should apply a filter to the "Order Date" attribute. Here’s how:

Open Data Module: Access the data module containing the table.

Apply Filter:

Filter Creation: Select the "Order Date" column and create a filter. Specify the criteria to include only newer entries, such as dates within the last year or a specific date range.

Save Filter: Save the filter to ensure it applies whenever the table is used in new reports.

Usage:

Report Design: When designing new reports, the filter will automatically apply, showing only the newer data as specified.

Applying a filter on the "Order Date" attribute allows for dynamic control over the data displayed without modifying the original table or creating duplicates.

Default Measure Property: Changing the Default measure property in a Crosstab impacts how measures are displayed.

Replacing Existing Measures: If a measure is already set on the Crosstab edges, changing the Default measure will replace the existing measure with the new Default measure.

Crosstab Updates: This change updates the Crosstab intersections to reflect the new Default measure, altering the displayed values accordingly.

Reference: The IBM Cognos Analytics V11.1.x documentation provides comprehensive details on Crosstab properties and the implications of modifying the Default measure, ensuring accurate data representation in reports.

Query Performance: Enhancing query performance involves various optimization techniques.

Avoid Functions in Filters: Using functions in filters can lead to slower query performance because functions often require additional computation and can prevent the database from using indexes efficiently.

Best Practices: It is recommended to simplify filters and avoid complex functions to ensure queries run faster.

Reference: IBM Cognos Analytics V11.1.x documentation suggests avoiding the use of functions in filters as a best practice for improving query performance.
