What can be used to define the first day of the week for reports in XMD?

The correct answer is related to how the first day of the week for reports is determined in the context of XMD (Cross-Market Data). Calendar Settings play a crucial role in this configuration, as they are specifically designed to define various aspects of the calendar, including the first day of the week.

By utilizing the Calendar Settings, users can establish preferences for week definitions, which can directly impact how weekly data is aggregated, visualized, and reported. This ensures consistency in reporting across different regions or departments that may have varying preferences for what constitutes the start of a week.

Other options do not serve this specific purpose. Week Start Configuration, while it sounds relevant, is typically associated with specific implementations or tools rather than a universal setting across all reports. Time Zone Settings focus on the geographical time considerations for data reporting but do not influence the week start definition. Weekly Reports Option is a feature that would pertain to the generation of reports on a weekly basis but does not have the authority to modify the foundational calendar settings that dictate the start of the week.
