Count rows based on two matching columns (static number)

[ACALDWELL8814]

Hello,

I am running into a bit of trouble creating a report of returned items. The report I am creating will show me the items returned in the last seven and the number of times they have been back historically. It would show something like the following: 

Part Number | Serial Number | Date of return | Number of times returned

If I filter the data on the reports page I am left with 1 in the number of times returned. To help compensate for this, I've tried to manipulate a column on the data page to count the number of times a part number (Column 1) and serial number (column 2) appear in my data and use that as a reference number that won't be affected by filtering date. 

So far I've tried to create a COUNTROWS function and a MAXX function with no success. I'm still very new to Power BI and DAX. Any help would be greatly appreciated.

Thanks,

Aaron

Hi,

Share some data and show the expected result.

To clarify, part number and serial number have to match to be a counted value. This is because there are similar serial numbers which have different part numbers and there are similar part numbers with different serial numbers.
