Dynamically rename column based on a mapping table

Hi,

 

I currently have in my database a table that looks like this:

tranpeter_1-1664483306300.png

 

 

We also have another table that provides the descriptive mapping for each generic column name. For example, CUSTOMER_ATTR_1 can be GEOGRAPHY for one customer and it can be COLOR for another customer.

When I display on PowerBI the data from the VALID_CUSTOMER_DATA.CUSTOMER_ATTR_1, I want to display CUSTOMER_INDUSTRY_ID. For CUSTOMER_ATTR_2, I want to display CUSTOMER_SALES_SEGMENT and for CUSTOMER_ATTR_3, I want to display GUIDANCE_GROUP.


Is this dynamic renaming of columns based on a mapping table doable in PowerBI?

 

Thank you!

-Peter
