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

Following procedure helped me solve this issue but i don't know why.

1. Cut the code in question given by the lines in the message
2. Save the query (e.g. to file)
3. Paste the code to where it was before
4. Again save the query

Even if it seems to be the same query executing it did not throw this error
