Scenerio: Recovered customer in a year - for a selected period, there is a time gap between 2 sales which is equal or greater than “Nr of Months before Lost”
No of months before lost (slicer of months) : 1, 3, 6, 12
I have a table have different customers and different sales date staring from 1 jan 2019 to 25 sep 2019
Ex: A customer has sales staring from jan 2019 then in feb then in june and then in aug
Want to calculate difference between every 2 sale dates for every customer in 2019...
Trying to implement loop functionailty:
No of customers =
Var FirstBuyInperiod = min (Sales[SALES_RECOGNITION_DATE])
Var NextSale = min(Sales[SALES_RECOGNITION_DATE]) > FirstBuyInperiod
Var looptable = GENERATESERIES(FirstBuyInperiod,max(Sales[SALES_RECOGNITION_DATE]))
Var looptable1 = ADDCOLUMNS(looptable, "datediff", Datediff(Firstbuyinperiod , NextSale , Month))
//here want to update the firstbuyinperiod and nextsale for 2nd iteration
set FirstBuyInPeriod = NextSale
set NextSale = min(Sales[SALES_RECOGNITION_DATE]) > FirstBuyInperiod
RETURN
COUNTROWS(CALCULATETABLE(VALUES(DimCustomer[CUSTOMER_NUMBER]),
FILTER(looptable1, [datediff]>= [No of month before lost slicer])))
Please suggest
