In the Optimized Design Experience, Data Analyzer is a new tool that replaces Explorer. Data Analyzer allows you to quickly create ad hoc analysis based on models or datasets. You can use Data Analyzer to explore data, create charts and tables, apply filters and calculations, and save your analysis as stories. Data Analyzer is similar to Explorer, but with some enhancements and new features, such as:

Support for both models and datasets

Support for planning models

Support for story calculations

Support for linked analysis

Support for responsive pages

Therefore, the correct answer isData Analyzer, as it is the tool that replaces Explorer in the Optimized Design Experience

When you create a story using a file as the data source, you automatically create an embedded dataset. A dataset is a collection of data that is imported into SAP Analytics Cloud and can be used in a story. An embedded dataset is unique to that story and cannot be shared outside the story or refreshed.You can transform or wrangle the data in the dataset to meet your story needs in the Data Preparation area

Chart scaling is a feature that ensures that you have a meaningful display of values across multiple charts in a story.By default, charts are not scaled, which can lead to incorrect data analysis, particularly if users are not paying attention to the actual values displayed in the chart1.

Chart scaling is applied to the following:

Specific page: Chart scaling is applied to all of the charts on a page, but the scaling may be different for the same measure on different pages, because the scaling factor is calculated separately for each page1.

Specific measure: Chart scaling is applied to a specific measure in a chart, and it affects all the charts that contain that measure on the same page.You can exclude charts from the scaling by selecting the chart and choosing Exclude from Scaling in the context menu1.

Chart scaling is not applied to the following:

All measures: Chart scaling is not applied to all the measures in a story, only to the ones that are selected for scaling.You can select which measures to scale by choosing Scale Measures in the context menu of any chart on a page1.

All pages: Chart scaling is not applied to all the pages in a story, only to the ones that have scaling enabled.You can enable or disable scaling for a page by choosing Enable Scaling or Disable Scaling in the context menu of any chart on a page1.

The SAP BW live model is a type of live data connection that allows you to access data from SAP Business Warehouse (BW) systems without importing it into SAP Analytics Cloud. The SAP BW live model supports the following calculation types:

Aggregation: You can use aggregation functions, such as SUM, COUNT, MIN, MAX, etc., to calculate the values of a measure based on a dimension or a filter.

Currency conversion: You can use currency conversion to convert the values of a measure from one currency to another based on predefined exchange rates.

Unit conversion: You can use unit conversion to convert the values of a measure from one unit of measurement to another based on predefined conversion factors.

The SAP BW live model does not support the following calculation types:

Dimension to measure: You cannot convert a dimension to a measure in a SAP BW live model.

Date difference: You cannot calculate the difference between two dates in a SAP BW live model.

Story calculation: You cannot create story calculations in a SAP BW live model.

Therefore, the correct answer isAggregation, as it is the calculation type that the SAP BW live model supports. Verified Reference:

You can define a calculation for a table in three ways:

Table: You can add a simple calculation by selecting two measures in a table, right-clicking, choosing Add calculation, and choosing the calculation you want.You can also add a repeating or single column or row to a table by right-clicking on a measure or dimension and choosing Add Calculation1.

Calculation editor: You can open the calculation editor from the drop-down menu of Measures or Dimensions in the Designer Panel and create complex calculations for a chart or table. For each type of calculation, a new calculated member is created.You can also use dimension attributes as part of a calculation2.

Story: You can create a calculated measure in the Builder pane of a story. When setting up your calculation, you apply the typical formula functions, conditions, and operators to the data contained in your model.Calculated measures allow you to perform mathematical and Boolean operations on your data1.
