Count the frequency of multiple IDs within a date period.

[Anonymous]

I have some phone data and would like to find out how frequently a customer calls multiple times within 5 days.

Short background, we have noticed some customers are calling again very shortly after their original call, and now I need to find out of common this is. 

So if a customer calls 3 times in October and then calls 2 times again in November I would like the total count to be 5. 

Customer ID	Date
1	01-10-2021
1	03-10-2021
1	04-10-2021
1	01-11-2021
1	02-11-2021

Is this even possible? The data is in an SQL server. I'm not an expert in Power Bi or SQL but is it perhaps easier to make this calculation with an SQL query?

Hi @Anonymous ,

Both Mahoneypat and AllisonKennedy offer great advice, sample data without sensitive information and expected output would help tremendously.

@Anonymous  Not sure yet what you want? Please describe further. The 5 is easy - just COUNTROWS(factTable) and put in a visual by Customer. Set a Date Range in filter or slicer visual. Then you can add DISTINCTCOUNT(CustomerID) to the same visual as the COUNTROWS(factTable) and you can get a tally of customers. Finally filter the visual for COUNTROWS(factTable) > 5 (or whatever value you wish).

However, if you want that rolling within 5 days, etc please further define your requirements, and if possible provide sample data and draw expected outcome in Excel sheet or pen and paper so we know what final numbers you expect.

You should be able to use a measure that simply uses DISTINCTCOUNT( ) of your Date column to get the # of days each customer called.  Or just do a COUNT of the CustomerID column to get the total # of calls.  When you make visuals that include month, etc. you will get the # of calls in that time period.
