how to calculate the number of buying for customers in one table

[Anonymous]

hello, I have one table like this

id customerID salesdate  salesamount

001   10001     20200101   200

002   10001     20200101   300

003  10003      20200102   400

004    10003    20200203    1000

.............

I need to create a measure to show the frequency of purchase for customers during a selected period , like this
frequency of purchase=switch( true(), count(customerID)=1, "one time", "more than one time"). but this measure can not work.

please guide me how to create this measure to show the frequency of purchase  for each customer

Hi, @Anonymous ;

Try it.

frequency of purchase = 
var _count=CALCULATE(COUNT('Table'[customerID]),FILTER(ALLSELECTED('Table'),[customerID]=MAX('Table'[customerID])))
return 
IF(_count=1,"one time", "more than one time")

The final show:

Hi, @Anonymous ;

Allselected() is to make the result vary according to the selected slicer. max(): [A]=max([A]) is also a method of grouping; here refers to the ID to calculate the count for the group.

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file.

Hi, @Anonymous ;

I am so sorry late reply due to account issues; you could create another measure.

count = CALCULATE(DISTINCTCOUNT('Table'[customerID]),FILTER('Table',[frequency of purchase]="one time"))

Thanks a lot! Now I understand it. Could I ask you further about this question? Now I can get the number of purchase frequency for each customer during the selected time period, and then I need to calculate for this time period, how many customers purchased only once, and how many purchased more than once.

also I found if I use a date slicer, the result can not change with slicer.

Thank you a lot!

May I ask you why you use 

ALLSELECTED('Table')

but not use only  'Table'. and why you use 

[customerID]=MAX('Table'[customerID])

Thanks again!

@Anonymous , refer to my video on segmentation. Use the count measure in place of the sum measure I used. Your Group by /values is customer

Dynamic segmentation -Measure to Dimension conversion: https://youtu.be/gzY40NWJpWQ

Bucket/Segment code
measure
Measure = Count(Table[id])

new Table
bucket = Generateseries(1,100,1)

new Measure
Countx(filter(Values(Table[customerID]), [Measure] = max(bucket[Value])), [customerID])

Buket should be used in visual

else

Sumx(Values(bucket[Value]) ,calculate( Countx(filter(Values(Table[customerID]), [Measure] = max(bucket[Value])), [customerID]) ))
