Create a Calculated Column from Different Tables
- Sorry that's my bad. I happen to work on a French system and it is using ";" rather than comma ",".
You need to replace all ";" by the proper separator which should be comma for you.
jhendrickson you are using DAX formula in Query Editor which is not allowed. You can use same expression, and to do so, close query editor and add new coloumn in your table and then add this DAX expression.
Here is link for your reference on how to add columns.
Thank you for the information. I tried this but now I'm getting a different error - A single value for the column can't be determined. I may have a bigger issue. Here is what I am trying to do:
I have one table listing school districts and building codes (multiple buildings per district) and another table with the pupils per district per year:
Table 1 Table 2
School Building Code School Year Pupils
AB 1000 AB 2018 200
AB 1001 AB 2017 300
CD 1002 CD 2018 400
CD 1003 CD 2017 500
etc etc
Finally I have a large table with all the raw financial information for all the districts, every transaction with a column for the year and the building code. I can do great charts of the financial information by school but I want to include a calculation of expenses per pupil. I want to be able to drill down to look at things like instructional expenses per pupil or transportation expenses per pupil in any given year. It seems like the only way to do this is to get a column in the financial information table which divides each transaction by the number of pupils per school, and the only way to get that is through the building code and year. Is there a formula which would look at the year and building code column in each row, then pull in the appropriate number of pupils?
share sample data in excel file and can give quick solution.
Hi jhendrickson,
Could you post your real table structures(including the relationships) with just some sample/mock data, and the expected result? So that we can further assist on this issue? It's better that you can just share a sample pbix file. You can upload it to OneDrive or Dropbox and post the link here. Do mask sensitive data before uploading. :smileyhappy:

This is a very truncated version of my data - thank you everyone for your help!
I was able to recover the number of pupil in a new column in your "Sheet1" table if that is what you were looking after.
However, the dataset seems very complicated for me, especially the management of the dates.
PowerBI works magic with dates so it would be better to have full dates using PowerBI Date functions rather that several columns with period, month names etc. just a thought.I created this column with the below DAX function:
Pupil number = var y=RELATED('Year'[Year]) var sc=RELATED(Schools[School]) var pupilnumber=CALCULATE(max('Pupil transposed (2)'[pupils]);'Pupil transposed (2)'[school]=sc;'Pupil transposed (2)'[year ]=y) return pupilnumberIs the below what you are looking for?
