## Next Week Function

I need a measure to calculate next week value. I already formated the data model that only include row in weekly level.

The next week value should be accomodated by two slicer: Filter 1 and Filter2

Any idea to create either measure/calculated column to achieve this result ?

The sample data model is in this link

Slightly amended the formula to take into account the first week as well

```next_week = CALCULATE(
SUM(Sheet1[Value]),
FILTER(ALL(Sheet1), IF(WEEKNUM(Sheet1[Date], 21)=51,0,WEEKNUM(Sheet1[Date], 21)) = IF(WEEKNUM(MAX(Sheet1[Date]), 21)=51,0,WEEKNUM(MAX(Sheet1[Date]), 21)) + 1
&& Sheet1[Filter1] = MAX(Sheet1[Filter1])
&& Sheet1[Filter2] = MAX(Sheet1[Filter2])
))```

Add tis formula on a measure:

```next_week = CALCULATE(
SUM(Sheet1[Value]),
FILTER(ALL(Sheet1), WEEKNUM(Sheet1[Date]) = WEEKNUM(MAX(Sheet1[Date])) + 1
&& Sheet1[Filter1] = MAX(Sheet1[Filter1])
&& Sheet1[Filter2] = MAX(Sheet1[Filter2])
))```

OR THIS

```next_week = CALCULATE(
SUM(Sheet1[Value]),
FILTER(ALL(Sheet1), WEEKNUM(Sheet1[Date]) = WEEKNUM(MAX(Sheet1[Date])) + 1
&& Sheet1[Filter1] = MAX(Sheet1[Filter1])
&& Sheet1[Filter2] = MAX(Sheet1[Filter2])
))```

Also it seems that you first YEARMONTHWEEK value may be wrong.

Hi, Thanks for the solution. Unfortunately I cannot use the WEEKNUM Function because  the week definiton is customized and changed according to users. Instead, i Have to use YEAR_MONTH_WEEK column (it is formated as integer).

Also the first date row, 23 Dec 2017 is intended as it is, because the date can be any, as long as it is on the date 1,8,15,23

I modified your measure, but it gives me nothing . Any advice ?

```next_week = CALCULATE(
SUM(Sheet1[Value]),
FILTER(ALL(Sheet1), WEEKNUM(Sheet1[WEEK_YEAR_MONTH]) = WEEKNUM(MAX(Sheet1[WEEK_YEAR_MONTH])) + 1
&& Sheet1[Filter1] = MAX(Sheet1[Filter1])
&& Sheet1[Filter2] = MAX(Sheet1[Filter2])
))```

You mentioned that you cant use weeknum function but you are using it in your formula.

Were you referring to something different?

Also the first YEARMONTHWEEK is wrong.

It says 20181204 and the relevant date is 23/12/2017

Solution Sage

Hi @andrehawari,

If you need your measure to be based on Year_Month_Week then try the below measure

```NextWeek =
var _weekn=RIGHT(MAX(Sheet1[YEAR_MONTH_WEEK]),1)
var _diff=IF(_weekn="4",97,1)
RETURN
CALCULATE(
SUM(Sheet1[Value]),
FILTER(ALL(Sheet1), Sheet1[YEAR_MONTH_WEEK] = MAX(Sheet1[YEAR_MONTH_WEEK]) + _diff
&& Sheet1[Filter1] = MAX(Sheet1[Filter1])
&& Sheet1[Filter2] = MAX(Sheet1[Filter2])
))```

If this helped you, please mark this post as an accepted solution and like to give KUDOS .
