Calcule number items of a group

[Anonymous]

Hello community

How can I calculate a number of items in the same table.

Exemple :

item	Months	Number of item per month
J	January	3
J	January	3
J	January	3
J	February	2
J	February	2
M	January	1

My column "Number of ielm per month" calculate the number of item group by month so the item J appears 3 times for the month January 

Thanks for your help

Try this measure:

Count of items per month = CALCULATE(
                            COUNT(Table1[item]), 
                                ALLEXCEPT(Table1, Table1[Months], Table1[item]))
