According to the SAP Help Portal1, SVG (Scalable Vector Graphics) is the recommended image file type for optimal story performance in SAP Analytics CloudStory Design. SVG is a vector-based format that can scale to any size without losing quality or clarity. SVG images also have a smaller file size than other image formats, such as JPEG, PNG, or BMP, which are raster-based formats that store pixel data. Raster images can lose quality or become blurry when scaled up or down, and they also have a larger file size than vector images. Therefore, using SVG images can improve the loading speed and responsiveness of your stories, as well as the visual appearance of your images2.

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 is Aggregation, as it is the calculation type that the SAP BW live model supports. Verified References:

When converting a story to Optimized Design Experience, you need to be aware that some elements that are available in the Classic Design Experience are not yet supported in the Optimized Design Experience. These elements include:

• Grid pages
• Linked analysis
• Geo maps
• Images
• Shapes
• Texts
• Buttons
• Input controls
• Value driver trees
• Explorer

If your story contains any of these elements, you will receive a warning message before converting the story, informing you that these elements will be permanently deleted from the story. You can choose to proceed with the conversion or cancel it. If you proceed, the unsupported elements will be removed from the story, and you will not be able to restore them1.
