In this Video, I’ll create a DAX (Data Analysis eXpression) Measure. This measure will be used to count the number of Invoices. The same measure will show the number of invoices for each Customer and the numbers of invoices for which each item appears.
DAX can be used in Microsoft Power BI, Microsoft PowerPivot, and MDX. It’s a relatively easy way to model your data.
Today’s DAX Expression:
Invoice Count := DISTINCTCOUNT(‘Sales Line Items'[Invoice #])
