In Power BI Desktop you are designing a data model. The FactOrders table contains a numeric column named SalesOrderNumber that stores unique order identifiers. Whenever you add this column to a visual, Power BI automatically aggregates it with a sum, which produces meaningless results. You must prevent any aggregation on the column by default while keeping its Whole number data type unchanged. Which column property should you modify to meet the requirement?
Change the Data category to Uncategorized.
Set Default summarization to Do not summarize.
Disable the Auto date/time option in File > Options and settings.
Enable Show items with no data for the column in the visual.
The unwanted aggregation occurs because Power BI assumes that numeric fields should be summarized. Changing the Default summarization property of the column to Do not summarize instructs Power BI to treat the field as an identifier, so it is shown in visuals without any aggregation. Adjusting data type, data category, or global model-wide options does not stop the automatic sum for that specific column.
