Which function can you use to support currency conversions in a CDS view?

The function designed specifically for handling currency conversions in a CDS (Core Data Services) view is CURRENCY_CONVERT(). This function is part of the foundational elements that allow developers to perform currency transformation directly within their models.

When utilizing CURRENCY_CONVERT(), the function effectively translates monetary values from one currency to another. It automates the process by considering current exchange rates maintained within the system, thus ensuring that the conversions reflect accurate and up-to-date financial information. This capability is essential for applications that require real-time financial analysis or reporting, as it allows insights to be rendered in a consistent currency format.

The other options do not correspond to established functions within the SAP ecosystem specifically for currency conversions in CDS views. While they may hint at being involved with currency handling, they are not the correct functions provided for such direct utility in the context of CDS. CURRENCY_CONVERT() is the recognized and standard approach for facilitating currency adjustments in these database expressions.
