A business analyst is creating a new app with sales dat a. The visualizations must meet several requirements: A Bar chart that shows sales by product…

The primary purpose of the master items library in Qlik Sense is to create reusable assets to ensure consistency and simplify app maintenance. The scenario explicitly states the Bar chart is "used in multiple sheets." Making it a master visualization allows the analyst to create it once and reuse it across the app. Any subsequent modifications to the master item will automatically propagate to all instances, which is the intended and most efficient use of this feature. The other visualizations (KPI, Treemap) are used only once, so the reusability benefit of making them master items is not applicable in this context.

A. Container: A Container is an object used to group other visualizations; it is not typically added to the master library for reuse in the same way as a chart.

B. KPI: The requirement states the KPI object is used only once, so there is no reusability advantage to making it a master item.

D. Treemap: The Treemap is used only a single time, which negates the primary benefit of creating a master visualization for reuse.

1. Qlik Sense on Windows Help, "Reusing visualizations with master items."

Section: Introduction.

Content: "If you want to reuse a visualization in other sheets, you can add it to the master items. ... This is useful when you want to have the same visualization on several sheets. When a master visualization is updated, the changes are applied everywhere the visualization is used." This directly supports creating a master item for the Bar chart which is used on multiple sheets.

2. Qlik Sense on Windows Help, "What are master items?"

Section: Master visualizations.

Content: "Master visualizations are charts that you can reuse in multiple sheets and for different purposes. A master visualization can be a chart that you have created, or a chart that is linked to a master visualization." This reference defines master visualizations by their reusability, which is the key factor in the question.
