OData v4 dates come over as ISO-8601 strings. Power BI’s OData feed connector loads them as text by default. To get a real date column, change the column type to Date/Time (or Date) in Power Query Editor — this is a one-time step per column. The connector doesn’t reshape SAP types on the way out; whatever the SAP service declares in metadata is what reaches Power BI.
Why do my SAP dates show up as text in Power BI?
