Views Aggregation

Views Aggregation

Views in SAP LeanIX can employ either a 1:1 mapping to the displayed fact sheets or a form of aggregation. For instance, each fact sheet correlates directly with a specific lifecycle in the lifecycle view. On the other hand, we use fields on relations or fields on related fact sheets to map one fact sheet to multiple target fact sheets. To visualize this view and its associated color, it's necessary to define a specific form of aggregation.

The chosen aggregation approach depends on the nature of the data and your preference. For categorical views, we might want to display the "best" or "worst" value. When working with numerical fields, we could aggregate values to their sum or average. While default aggregation values can be changed within the data model according to your needs, you can choose the view aggregation method from an additional dropdown next to the View dropdown.

This chosen view and aggregation settings can be saved as a bookmark. This ensures that only relevant options—such as sum/average for numerical fields and min/max for categorical fields—are displayed. If a view is changed, the default aggregation configured in the meta model is applied until you decide to change it via the dropdown. If you save the view with its current default aggregation, bookmark it, and later change the default in the meta model, the updated default will be applied when you reload the report with the bookmark.

This ensures flexibility and customization while maintaining a clear and intuitive interface.

Selecting a Related Fact Sheet

In addition to the aggregation options, the dropdown menu includes an option that extends customization via the meta model, allowing you to select a specific target fact sheet. This option bypasses aggregation entirely, only offering the view for the selected fact sheet's value.

By selecting a related fact sheet, you can gain detailed insight into a particular data point without the distortion of aggregated data. This can be particularly beneficial when you want to isolate and scrutinize one aspect of your data, sidestepping the broader perspective typically provided by aggregation.

You can select a related fact sheet from the aggregation dropdown next to the View dropdown. Selected view can be saved to a bookmark for future reference. Any changes to the fact sheet, such as adding or removing relations or altering its display name, are automatically updated in the bookmark as well when reopened.

Obsolescence Risk View Aggregation

The aggregated obsolescence risk is calculated based on the lifecycle status of the underlying IT components that support your applications. The calculation for aggregated obsolescence risk considers all IT components related to an application in the following ways:

• Directly linked IT components: IT components that are directly linked to the application via the relApplicationToITComponent relation and are active are considered. Inactive relations are excluded; the 'active from/until' field in the relation between IT components and applications determines the active or inactive status.
• Indirectly linked IT components: These are IT components indirectly connected to an application either through hierarchical relations relToChild between IT components or as required/required by relations relToRequires between IT components.

  📘

  Note

  relToRequires relations directly between IT components and applications are not considered.

• Indirectly linked via other applications: IT components indirectly connected to the application through another application with an active hierarchical relation relToChild are also included in the risk assessment.

The following order, from highest to lowest, indicates the severity of the risk status of applications:

• Unaddressed End Of Life
• Unaddressed Phase Out
• Missing Lifecycle Information
• Missing IT Component Information
• Risk Accepted
• Risk Addressed
• No Risk

Obsolescence Risk Details

By selecting an application in the report, you can understand the factors contributing to its obsolescence risk score. Selecting an application opens the side panel in landscape, matrix, and roadmap reports, providing you with all the relevant details about the selected application.

You can identify all the fact sheets contributing to the overall risk score and see the weight or severity of each contributing IT component's status. This provides a clearer understanding of the relationships between applications and IT components, enabling better risk management and decision-making.
