Dax calculation to filter out values basis on scenarios given in the same table

[Anonymous]

Hi everyone,
I have a table_1 which has columns ( qty, procurement,week)
so under qty there are values, Under procurement we have different categories (1,2,3,4). Under week we have ( week 1-20)
So I have to create a measure to get a value when,
[( Values from qty which are of 2nd category only and week from 11-16 only (subtract) Values from qty which are of 4th category and week from 11-16 only ( divide) Values from qty which are of 2nd category only and week from 11-16 only ]
Pardon me If I am not conveying it in proper way as I am new to the community and powerbi.
Thanks

hi @Anonymous 

try like:

Measure = 
VAR _value1 =
CALCULATE(
    SUM(TableName[qty]), 
    TableName[Procurement]=2, 
    TableName[week]>=11,
    TableName[week]<=16
)
VAR _value2 =
CALCULATE(
    SUM(TableName[qty]), 
    TableName[Procurement]=4, 
    TableName[week]>=11,
    TableName[week]<=16
)
RETURN
DIVIDE(_value1 - _value2, _value1)
