Check Orders Within A Given Date

Hi All,

I'm new to Power BI. For my 1st project I am trying to determine if an order came from a marketing campaign.

I have a list of campaigns, the customers involved and the start and end date they ran from.

What I am trying to figure out is for every order is the customer in a campaign and have ordered between the start and end date the campaign ran for.

Hope this makes sense. 

I have set up 3 spread sheets:

Campaign Audience

Campaign ID

Customer ID

Campaigns

Campaign ID

Campaign Name

Start Date

End Date

Orders

Customer ID

Order Date

Product

Thanks in advance.

Michael
