When designing Dimensionally Modeled Relational (DMR) structures in Framework Manager, understanding how determinants influence hierarchy levels is crucial. Here is an explanation:

Determinants in Framework Manager: Determinants are used to define the granularity of data and how it is grouped. They are essential in DMR models to ensure correct aggregation and drill behavior.

Hierarchy Levels: The order in which determinants are defined in a query subject influences the hierarchy levels. Higher-order determinants represent higher levels in the hierarchy, while lower-order determinants represent more granular levels.

Configuration: Configure determinants in the properties of a query subject. The sequence of determinants determines how data is aggregated and navigated in reports.

Impact on OLAP Behavior: Properly ordered determinants ensure that measures and dimensions behave correctly, allowing users to drill down and roll up data accurately in reports.

Enriching Framework Manager Packages: Enriching packages enhances the data available for AI-driven functionalities in dashboards and explorations.

Permissions Required: To enrich a Framework Manager package, users must have the necessary permissions, specifically read, execute, and traverse permissions for the package.

Functionality Access: Without the appropriate permissions, users will not be able to access the enrich package functionality.

Reference: IBM Cognos Analytics V11.1.x documentation specifies the need for these permissions to perform enrichment operations on Framework Manager packages.

To combine several images and text objects into one object in a dashboard, follow these steps to group the objects:

Select Objects: In the dashboard editor, select the images and text objects that you want to combine.

Group Objects: Use the "Group" option available in the toolbar or right-click menu to group the selected objects. This creates a single group object that can be moved and aligned as a unit.

Adjust Group Properties: You can adjust the properties of the group as needed, such as alignment, size, and position.

Grouping objects simplifies the management of multiple items, making it easier to move and align them within the dashboard layout.

Regarding custom sorts in IBM Cognos Analytics dashboards, here’s the correct information:

Creating Custom Sorts:

Applicable Data Types: Custom sorts can be created on dimensions and categorical data but not on measures. Measures are numerical values used for calculations and aggregations, and sorting them customly is not supported in the same way as categorical data.

Implementation:

Procedure: To create a custom sort, select the field from the source pane, right-click, and choose the sorting options from the properties menu. Specify the custom sort order as required.

Limitations:

Non-measures Only: Ensure you are applying custom sorts to non-measure fields, such as dimensions or attributes, to control the order in which data is displayed in visualizations.

Custom sorting enhances the presentation and analysis of data by allowing users to define specific order criteria.

Query Cache: The query cache in IBM Cognos Analytics helps to store the results of frequently executed queries to improve performance.

Avoiding Roundtrips: When the same master-detail request is executed repeatedly, the query cache can serve the results from the cache instead of making another roundtrip to the database.

Performance Improvement: This reduces the load on the database and speeds up the report generation process by utilizing the cached data.

Reference: IBM Cognos Analytics V11.1.x documentation details the functionality of the query cache, including its ability to handle repetitive master-detail requests efficiently by avoiding unnecessary database roundtrips.

Using the Assistant: The text-based Assistant in IBM Cognos Analytics can help quickly create dashboards by understanding natural language commands.

Creating a Dashboard: By entering 'show data', the Assistant lists available data sources. After selecting a data source, entering 'create dashboard' or 'build dashboard' prompts the Assistant to generate an initial dashboard.

Efficiency: This method provides a fast and user-friendly way to initiate dashboard creation, leveraging AI to streamline the process.

Reference: The IBM Cognos Analytics V11.1.x documentation explains the capabilities of the Assistant, including the steps to create dashboards using simple text commands, ensuring ease of use and quick setup.

Drill-through Definition: Drill-throughs in Cognos Analytics allow users to navigate from one report or visualization to another, typically to see more detailed information.

Passing Data Points: Data points can be passed to the target Drill-through provided the data sources have matching values. This ensures continuity and relevance in the data being analyzed.

Targeting Other Dashboards and Reports: Developers can set up Drill-throughs to link to other dashboards or reports, facilitating deeper analysis and better data exploration.

Cognos Documentation: IBM Cognos Analytics V11.1.x documentation provides guidelines on creating and managing Drill-throughs, including passing parameters and targeting various types of reports and dashboards.

When the Drill-through target type is set to Bookmark in IBM Cognos Analytics V11.1.x, the following types of saved report outputs can be used:

HTML:

Interactive Output: HTML outputs are interactive and support bookmarks, allowing users to navigate to specific sections within the report.

Usability: Ideal for web-based viewing and interaction.

PDF:

Static Output: PDF outputs support bookmarks and provide a static, paginated format that is useful for printing and sharing.

Accessibility: Bookmarks in PDFs enhance navigation within long documents.

These output types leverage the bookmark functionality to improve navigation and user experience.

Joined Views in Data Modules: When creating joined views in Cognos Analytics, the order of joins and evaluation is significant.

Execution Logic: The joined view of tables (a and b) is first evaluated. The result of this join is then used to perform the subsequent join with table (c).

Post-join Evaluation: This approach ensures that the initial join logic is preserved and applied before the next join is executed.

Reference: The IBM Cognos Analytics V11.1.x documentation outlines the process of creating and using joined views, detailing how the execution logic is handled by the database.

To create a Layout Component Reference in a report in IBM Cognos Analytics V11.1.x, you need to provide the "Name" property. Here are the steps:

Define Component: Identify the component you want to reference in your report layout.

Set Name Property: Assign a unique name to the component in its properties. This name will be used to reference the component.

Create Layout Component Reference: In the report where you want to use the component, add a Layout Component Reference and specify the name of the original component.

Reference the Component: The referenced component will be displayed in the new location, allowing you to reuse layout elements across multiple reports.

Using the "Name" property ensures that components can be easily referenced and maintained.

Render Variable: This is used to conditionally show or hide objects within a report based on the value of a variable.

Application: By setting a render variable, you can control the display of the list object based on certain conditions. If the condition evaluates to true, the object will be shown; if false, it will be hidden.

Cognos Documentation: The IBM Cognos Analytics V11.1.x documentation highlights the use of render variables to manage report object visibility without affecting the data processing logic.
