Matrix - Use Row values to text search in another column and filter returned matrix values

[PowerBIPerson42]

Hello,

I've been stuck on this for a few days and am grateful for any help!

Right now I have three tables in my data model: A Transcript data table, a Subject list of unique subjects, and a Course Information lookup table.

Within the course information table their is a 'subjects' column where each course has multiple subjects listed. I'm hoping to create a matrix like the example below where the 'subjects' column in the course information table is filtered to results that contain the unique subject listed in each row. The values for enrollments, completions, total hours, etc. would then calculate for courses in the filtered transcript data table that contain the subject.

In reality, there are 32 unique subjects and 7 columns to the table so I'm hoping to not write a measure to CALCULATE for every column searching by a subject manually listed.

Subject	Enrollments	Completions	Total Hours
Leadership	1000	943	850
Software	550	500	480
Project Management	620	221	240

@PowerBIPerson42 I would recommend putting sample data in excel file and expected output (which kind of you shown here) and share excel file here, you can share using one drive/google drive and we will able to help to put the solution together.

Hi @parry2k ,

Thank you for your response! I was finally able to figure it out, actually.
My error was in how I was thinking about the subject lookup part of the data model and trying to create a measure or column was not the right approach. 
I ended up using Transform Data to make a duplicate of the course information table and then used Split Column to create a new row for each of the subjects listed on a course. This allowed me to use the new column with one subject per cell as the row value in the matrix - which then filters down the below course information and transcript information by each subject.

I'm fairly new to data modeling and Power BI and sometimes have a hard time determining when to change something in a data model vs when to write a measure vs when to use a filter on a visualization vs etc..
