Calcular clientes ativos

Hi  LuanRamos,

Here are the steps you can follow：

1. Create a calculated column.

purchase=
var _3monthbefore=
CALCULATE(
    COUNT('Table'[Amount]),
    FILTER('Table',
[Cod_Cliente]=EARLIER([Cod_Cliente])
&&
MONTH([Date])=MONTH(EARLIER([Date]))-3))

var _2monthbefore=
CALCULATE(
   COUNT('Table'[Amount]),
    FILTER('Table',
[Cod_Cliente]=EARLIER([Cod_Cliente])
&&
MONTH([Date])=MONTH(EARLIER([Date]))-2))

var _1monthbefore=
CALCULATE(
    COUNT('Table'[Amount]),
    FILTER('Table',
[Cod_Cliente]=EARLIER([Cod_Cliente])
&&
MONTH([Date])=MONTH(EARLIER([Date]))-1))

var _flag=
SWITCH(
    TRUE(),
    _1monthbefore =1||_2monthbefore=1||_3monthbefore=1, "One time purchase",
     _1monthbefore >1||_2monthbefore>1||_3monthbefore>1,"Multiple purchases",
    "No purchase")

return _flag

2. Create measure

PURCHASE TIME =
var _month=SELECTEDVALUE('Month'[Month])
RETURN
IF(
    MONTH(MAX('Table'[Date]))>=_month-2&&MONTH(MAX('Table'[Date]))<=_month,
    1,0)

3. Result.
