Can I create the expected table with power query in excel?

And how to do that?

Thank you

Open your Excel workbook with the two tables

Go to the Data tab in Excel.
Click on Get Data and select Combine Queries and then Merge.
Select "Inner" for the join type

what should I do in power query if I want to lookup the Company product code like the expected table?

Because 1 Customer product code has some Company product code in a specific month

thank you

Hi @Mars3442 ,

Please try use merge queries in power query:
