貴社の営業部門向けに、Microsoft ExcelからデータをインポートするPower BIレポートを公開します。 Microsoft SharePointのフォルダ内に配置しました。データモデルには複数のメジャーが含まれています。 既存のデータからPower BIレポートを作成する必要があります。開発作業を最小限に抑えたソリューションが求められます。 どのタイプのデータソースを使用すべきですか?
正解:D
When you publish a report to the Power BI Service, the data and the measures you created are stored as a semantic model. By connecting to this existing dataset, you gain several immediate advantages: Minimizes Development Effort: You don't have to recreate the complex measures (DAX) or the data relationships. They are already "live" and ready to use. Single Source of Truth: Since the original report is already importing data from SharePoint and Excel, connecting to the dataset ensures your new report stays perfectly in sync with the original. Reduced Overhead: You avoid building a second, redundant data refresh process for the same Excel file.
