Looking for Tips on Storing Data

[utsavlexmark]

Hello,

I am an Digital Marketing Professional and recently started using Power BI for representing data to the stackholders. Currently I am working with a simple data which I need to present with lots of complicated calculations. Here are the headings of data I am working with:

partnumber	mktname	totquantity	Week	Year

 Week and Year is for Slicer; main issue is with other fields.

“totquantity” field contains data of how much units have been sold and all the data is flagged with week and year. Now let me explain what my requirement is:

Suppose I select Year “2018” and Week “42” in slicer; “totquantity” will show week 42 data naturally – along with that I want 3 other columns will be there where I can see “totquantity” of Week 41, Week 40 and Week 39 respectively.

 First of all I don’t whether I able to explain the situation properly or not; if not please let me know – I will try to explain it as much as possible.

Secondly, I don’t whether the requirement is technically possible or not.

I am open with all type of reply.

@utsavlexmark If you can post some sample data and expected output that will be helpful to understand better.

Hello pattemmanohar,

Thanks for your reply. Here I am trying to provide the info you need. Please let me know if you have more doubts, I would love to explain.

Database

Partnumber	Mktname	Totquantity	Week	Year
A0001	Product A	1	42	2018
A0001	Product A	2	40	2018
A0002	Product B	2	42	2018
A0002	Product B	1	39	2018
A0003	Product C	1	42	2018
A0003	Product C	2	41	2018
A0004	Product D	2	42	2018
A0004	Product D	1	40	2018

Output

Slicer 1=Week=42(selected)       Slicer 2=Year=2018(selected)

Partnumber	Mktname	Totquantity(Week39)	Totquantity(Week40)	Totquantity(Week41)	Totquantity(Week42)
A0001	Product A	0	2	0	1
A0002	Product B	1	0	0	2
A0003	Product C	0	0	2	1
A0004	Product D	0	1	0	2

Hi @utsavlexmark

Create measures in your table

measure =
CALCULATE (
    SUM ( Sheet2[Totquantity] ),
    FILTER (
        ALLEXCEPT ( Sheet2, Sheet2[Mktname], Sheet2[Partnumber] ),
        [Week]
            = SELECTEDVALUE ( Sheet2[Week] ) 
            && [Year] = SELECTEDVALUE ( Sheet2[Year] )
    )
)

measure1 =
CALCULATE (
    SUM ( Sheet2[Totquantity] ),
    FILTER (
        ALLEXCEPT ( Sheet2, Sheet2[Mktname], Sheet2[Partnumber] ),
        [Week]
            = SELECTEDVALUE ( Sheet2[Week] ) - 1
            && [Year] = SELECTEDVALUE ( Sheet2[Year] )
    )
)

measure2 =
CALCULATE (
    SUM ( Sheet2[Totquantity] ),
    FILTER (
        ALLEXCEPT ( Sheet2, Sheet2[Mktname], Sheet2[Partnumber] ),
        [Week]
            = SELECTEDVALUE ( Sheet2[Week] ) - 2
            && [Year] = SELECTEDVALUE ( Sheet2[Year] )
    )
)

measure3 =
CALCULATE (
    SUM ( Sheet2[Totquantity] ),
    FILTER (
        ALLEXCEPT ( Sheet2, Sheet2[Mktname], Sheet2[Partnumber] ),
        [Week]
            = SELECTEDVALUE ( Sheet2[Week] ) - 3
            && [Year] = SELECTEDVALUE ( Sheet2[Year] )
    )
)

current week = IF([measure]<>BLANK(),[measure],0)

current week-1 = IF([measure1]<>0,[measure1],0)

current week-2 = IF([measure2]<>BLANK(),[measure2],0)

current week-3 = IF([measure3]<>BLANK(),[measure3],0)

@v-juanli-msft, after a long time I need to resume this post again. Initially I thought this process is working perfectly - but now I found some discripencies are there in the process.

Let me try to explain the situation; currently I have included data till Week52(current week). When I am creating the table Week 52, Week 51, Week 50 and Week 49 is showing. I have created one column for avarage of last 4 weeks. We have one process to validate this data and forund in the table data are matching. But the Avearge of Last  4 Weeks is not matching.

When I downloaded the Dashboard data, I found Downloaded data of Week 50 is not matching with what I saw in table and that is the reason the last 4 Weeks Average is not matching.

Detail analysis is showing that this problem is occuring randomly for different weeks.

I guess you defenitely have a solution for this issue.

Hope I am clear with the explation - if not please let me know.

@utsavlexmark That means, if you select week 40 then you want to display week 39 and week 40 data only isn't it ? 

[utsavlexmark]

No, what I want is - when I will select a week in Slicer - in the table data of that week and preceeding 3 weeks will be shown. This is actually to see how a particular product is performing in last 4 weeks including the selected week.
