Let’s get started:

Import below sample dataset into Power BI desktop-

Id	Statement	Rating
1	Service	5
2	Food Quality	5
3	Atmosphere	7
4	Value for money	5
5	Cleanness	7
6	Staff Frienliness	2
7	Coffe Quality	6

Now follow these steps-

Step-1: Add one new column , Right click on dataset and select “New Column” and write below DAX function.

Find char position = FIND("r",Survey[Statement], , -1)

Step-2: Here we want to find “r” character position for all values of Statement column. Now click on Data tab and you can see the position number. It will return -1, if not found character in string.

Step-3: Find DAX is case-sensitive, now pass “R” in first parameter.

You can see in above screen shot, capital “R” is not exist in string that’s why DAX returns -1 for all.
