I need to display Average of a calculated column on basis of month wise data

[vishalpat13]

Hi Team,
So, I have a power Bi task at hand where I have created a dashboard . Issue is I need to display average of a calculated column by month

for eg; I have a column with name CSM readiness

CSM readiness = csm1 + csm 2
-----------------------------------------------------------------
Campaign Id CSM readiness
123 7
456 6
321 8
789 9
003 3

Presented above is an example where you can consider CSM readiness as the calculated column
Now, for different Ids, I am getting this value while I put slicer as filter for month



So, Please help me in getting the average of this CSM readiness column while indicating USE Relationship also because month is a part of inactive relationship
