Count instance of string in column

[gingerclaire]

I have a table (L&L) as below which is connected to my date table:

Date           Job role codes concatenated

01/11/22      123b4, 34b56, 2b343, 3a421

03/11/22       123b4, 34b56, 2b343, 3a421

3/10/22         123b4, 34b56, 2b343, 3a421

I have another table containing the codes and definitions:

123b4 Vet

34b56  nurse

3a421 manager

I want to end up with a pie chart or table showing:

Job role

Vet        3

Nurse      2

Manager       4

How do I relate these two tables and make this happen please?

@gingerclaire You can either use Power Query Editor to split that column on commas and the unpivot or you could do this:

Measure = 
  VAR __Code = MAX('Table2'[Code])
  VAR __Table = FILTER('Table1',CONTAINSSTRING([Job role codes concatenated],__Code))
  VAR __Result = COUNTROWS(__Table)
RETURN
  __Result

Thank you! I used this and it is working in a table BUT it is using COUNTROWS so is giving me the wrong totals - but i think i worked out why!

One a single row there might be several instances of the same string i.e. each row is an event and there might be 5 or six vets at that event. So it needs to count how often the string/code appears.

Is there a way to do this please?
