SQL Server: Invalid Column Name

Question

I am working on modifying the existing SQL Server Stored Procedure. I added two new columns to the table and modified the stored procedure as well to select these two column

Answer 1

There can be many things:
First attempt, make a select of this field in its source table;
Check the instance of the sql script window, you may be in a different instance;
Check if your join is correct;
Verify query ambiguity, maybe you are making a wrong table reference
Of these checks, run the T-sql script again
