WoW change but it shows as blank

[Anonymous]

Hi guys,

I'm trying to do a WoW change for bag packing rate, but it shows up as blank. There's only one date in each week.

Here's the DAXs i created:

WoW change:

WoW Uplift_Packingrate =

VAR LW_PackingRate =

    CALCULATE(

        [Packing Rate],

        FILTER(

            All('Training Performance'),

            'Training Performance'[As of ]=[LW_date])

    )

RETURN

    DIVIDE([PackingRate_TW]-LW_PackingRate, LW_PackingRate,0)

Here's the DAX for LW_Date:

LW_date =

var TW_date = max('Training Performance'[As of ])

return CALCULATE(

    max('Training Performance'[As of ]),

    'Training Performance'[As of ] < TW_date

)

Do you know how to solve this?

Thanks a lot

Wenlu

@Anonymous , For Week on Week, use a date table and Week Rank or Week table and Week Rank. Rank on Week Start Date or Year Week (YYYYWW)

example

Column needed

Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)

oe

Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense)

Measure
This Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))
Last year Week= CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -52)))
last two weeks = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]<=max('Date'[Week Rank])-1
