Type 1 SCDs in Power BI

Soheil Bakhshi grabs some Excel data from SharePoint:

We have a retail company selling products. The company releases the list of products in Excel format, including list price and dealer price, every year. The product list is released on the first day of July when the financial year starts. We have to implement a Power BI solution that keeps the latest product data to analyse the sales transactions. The following image shows the Product list for 2013:

So each year, we receive a similar Excel file to the above image. The files are stored on a SharePoint Online site.

Read on to see how it works. Of course, the data source itself doesn’t affect how you implement slowly-changing dimensions, so the technique Soheil shows applies to a broad number of use cases.
