column value based on the values from two other columns
Hi, I am looking for help if it is possible to add a column value based on the values from two other columns.
I have two possible values for the Class Name column based on the Course Name and whether a student is in 7 or 8 Grade.
The Class Name values need to be either "7 Mathematics" or "8 Mathematics". The first image below is what I am hoping for it to look like.
If this addition below can be added it would be fantastic!
If the Course Name value is any of these with the green checks that name would just be duplicated in the Class Name column.
So basically copy the Course Name values to the Class Name column unless they are math classes and then assign either of the two corrected values.
1. Identify a primary key in your data. In your case that is a composite key made up of Course Name and Student Grade which I implemented as a calculated column
2. Right click on that primary key column and create (or edit) a group. Now you can bucket collections of primary keys into your Class groups.
3. Use the Class groups column in your visuals.
The same can be achieved with lots of code in either Power Query or DAX, but the column group method is more convenient, and it is sufficient if you don't expect your data to change frequently.

Read about Column Groups. Much easier to create and maintain.
lbendlin thanks, I will check it out.
lbendlin I did some reading on that and appreciate you steering me to a totally new area that I have not used in PBI before. I still cannot figure out how to apply that to my desired outcome.

lbendlin Thank you very much for your continued help. Below is some sample data with the results field being the Class Name column. Most of the values are the same as the Course Name column. All students need to be in either 7 Mathematics or 8 Mathematics based on their grade level and regardless of what actual math class they are in.
