Calculate distinct count

Hi Aniket_Bhande ,

You can create a measure as below to get it and put it on your visual:

Measure = DISTINCTCOUNT ( 'Table'[CUST NAME] )

f the above one can't help you get the expected result, please provide some raw data in your table (exclude sensitive data) with Text format and your expected result with backend logic and special examples. Does the field [customer population] and [customer name] come from the same table? It is better if you can share a simplified pbix file with the expected result explanation. You can refer the following link to upload the file to the community. Thank you.
