SUM Column if Date is equal to or 6 days greater than another date

[Serdet]

Hey community,

Dataset 1

Week Commencing Date	Earned Hours	Expended Hours	Productivity (Earned Hours / Expended Hours)
06/01/2023	10	20	0.5
13/01/2023	10	5	2

Dataset 2

Created Date	Difference
07/01/2023	1
15/01/2023	2

I need to create a measure that reads as follows:

(If 'Created Date' is equal or + 6 to 'Week Commencing Date' then SUM difference. + 'Earned Hours') / 'Expended Hours'

Can anyone help me with this DAX?

Hi , @Serdet 

According to your description, you want to get the "(If 'Created Date' is equal or + 6 to 'Week Commencing Date' then SUM difference. + 'Earned Hours') / 'Expended Hours'" in datest 2.

In my uderstand , when the [Created Date]=2023/1/7 then we search the [Week Commencing Date]=2023/1/7 or 2023/1/13, then we sum the difference in dateset 2 , this sum of difference is =1  when the [Created Date]=2023/1/7. The 'Earned Hours' in dataset 1 is =10. The  'Expended Hours'" in dataset 1 is =5.

If this , here are the steps you can refer to :My test data is the same as yours.

[1]If you want to add a calculated column in dataset 2 , you can click "New Column" and enter this:

Column =
var _date =  {[Created Date],[Created Date]+6}
var _t = FILTER('Table','Table'[Week Commencing Date] in _date)
return
DIVIDE([Difference] + SUMX(_t ,[Earned Hours]) ,  SUMX(_t ,[Expended Hours ]))

The result is as follows:

[2]If you want to add a measure, you can use this dax code:

Measure = var _cur_createdDate = MAX('Table (2)'[Created Date])
var _date =  {_cur_createdDate,_cur_createdDate+6}
var _t = FILTER('Table','Table'[Week Commencing Date] in _date)
return
DIVIDE(SUM('Table (2)'[Difference]) + SUMX(_t ,[Earned Hours]) ,  SUMX(_t ,[Expended Hours ]))

The result is as follows:

If this method does not meet your needs, you can provide us with your special sample data and the desired output sample data in the form of tables, so that we can better help you solve the problem.

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
