Hello everybody,
I've got a table like:
id | timestamp | uid | tariff_name |
1 16.01.2017 id001 tariff_A
2 16.01.2017 id002 tariff_A
3 17.01.2017 id001 tariff_B
4 18.01.2017 id002 tariff_C
5 18.01.2017 id003 tariff_A
How can i count: all purchases for id001 made after purchasing tariff_A ? (1 purchase for example table)
sum of id that purchase smth after purchasing tariff_A? (2 (id001 & id002 id for example table)
hi @Anonymous
you could do a calc column like this
CntLaterPurchases = CALCULATE( COUNTROWS( FILTER( table, AND( table[uid] = EARLIER(table[UID]), table[id] > EARLIER(table[id]) ) ) ) )
HTH,
Frank
hi @BetterCallFrank thanks for reply, i've got the following error: "EARLIER/EARLIEST refers to an earlier row context which doesn't exist", what can i do wrong?)
And what about if the first purchase was tariff_B, then tariff_A, and then tariff_C - i need to count only tariff_C - is it possible with your suggestion?
Hi @Anonymous
for your first question, try this measure:
Cnt Later Purchase of Customer:=
IF( HASONEVALUE(Table1[uid] ), VAR TheUID = VALUES( Table1[uid] ) VAR TheID = MAX( Table1[id] ) RETURN COUNTROWS( FILTER( ALL( Table1 ), AND( Table1[uid] = TheUID, Table1[id] > TheID ) ) ) )
