IF Countif calculation in DAX?

[analyst31233]

I have a very useful excel formula I use to check if a Company ID exists in another sheet with a value of "Yes", and if so, to return "Yes", but if not, to return "No". How can I create this exact same calculation in DAX?

The objective is to check if there is a Company ID, AND that the "Response" column is "Yes", because there can be multiple CompanyID. Both tables are in Power Pivot, if that helps.

=IF(COUNTIFS(Vendor_List, [@[Company_ID]], Email_List, "Yes")>0,"Yes","No")

Company_Table:

Company_ID	Response of Yes?
123	=IF(COUNTIFS(Vendor_List, [@[Company_ID]], Email_List, "Yes")>0,"Yes","No")
124	=IF(COUNTIFS(Vendor_List, [@[Company_ID]], Email_List, "Yes")>0,"Yes","No")

Email_Table:

Email	Company_ID	Response
123@aol.com	123	No
123@aol.com	123	Yes
124@aol.com	124	No
124@aol.com	124	No
124@aol.com	124	Yes
