Calculate percentage using two count columns by year

[GeorgeColl]

I have searched for a solution but can't seem to get them to work in my specific situation.

I have two columns that I'm using: a count for the number of claims in one column and a second column is a count of the number claims that have had someone appointed to them, I then have this shown by year. I want to have a column showing the percentage of claims that have had someone appointed to them. Example table below is what i'm looking for including the % Appointed column I want to calculate. I have added an example of the data table below

Year	Count of ClaimRef	Count of appointed	% Appointed
2017	100	10	10%
2018	10	10	100%
2019	100	10	10%
2022	40	20	50%
Total	250	50	20%

Any help would be much appreciated

EDIT:

 The table I've shown above was my desired output. My data table would look like the following:

ClaimRef	Year	Appointed
1234	2020	Name1
1235	2021	Name2
1236	2020
1237	2021
1238	2022	Name3

In my output table (being shown in the report) I'm using a count of ClaimRef and a count of appointed (i.e. the claims where someone is appointed).

Sorry if it wasn't clear, the table I've shown was my desired output. My data table would look like the following:

ClaimRef	Year	Appointed
1234	2020	Name1
1235	2021	Name2
1236	2020
1237	2021
1238	2022	Name3

In my output table (being shown in the report) I'm using a count of ClaimRef and a count of appointed (i.e. the claims where someone is appointed).

You can add a new column with the code below:

% Appointed = FORMAT(DIVIDE('Table'[Count of appointed],'Table'[Count of ClaimRef]),"00%")
