Distinct count of products that fell into a category during a certain time period

[bernate]

Hello, I am trying to get a distinct count of products that fell into a category during a certain time period.

• The "Archived" table contains the categories products fall into, depending on how they were classified at the time. The "Archived" table also has a Doc Version Date field based on when the document version went into effect. The Doc Version Date field contains duplicates because groups of categories are updated at once on one date.
• The "Product" table contains product information and an initiation date. The Product ID and Initiation Date fields may contain duplicates.
• The "Date Table" contains unique Date Key fields.

Product is connected to Date Table on DateTable.DtKey--->---Product.Initiation Date. Archived is connected to Date Table on Archived.DocVersionDate ---<>---DateTable.DtKey.

I want to know the distinct count of products that fell into a category during a certain time period. For example, between 2/21/2019 and 09/8/2019, there were 540 products that had an initiation date during that time. I want that number (540) displayed in the Doc Version Date of 02/21/19 because that's how many products were initiated before the new Doc Version on 09/09/2019.

Is there a simple way to do this using a measure, or would I have to alter something in my model or in Power Query to get this to work?

Hi, please try this link. I added the PBIX file and the Excel file where the tables come from.

Below is the result I am wanting in the second table visual.
