Calculate CY sales based on weeks

[ns292022]

Hello Friends,

I have the following table, where datediff is the difference in weeks from current date

The output should be:

I created a new column Name using the formula: 

Name = if(Enrolment_new[datediff]=1,"Last Week",if(Enrolment_new[datediff]<=4 && Enrolment_new[datediff]>0 ,"Last 4 Weeks",if(Enrolment_new[datediff]<=12 && Enrolment_new[datediff]>0,"Last 12 Weeks",if(Enrolment_new[datediff]<=52 && Enrolment_new[datediff]>0,"Last 52 Weeks"," "))))

However the summarize table is excluding Last Week data from Last week 4 weeks data, Last 4 weeks data from Last 12 weeks data and so on. Can someone help me on how to get data in correct form where CY, PY values of Last 4 weeks should include Last week and so on.

Thanks!

Hi @ns292022 ,

Please share some sample data in text format so that we could test formulas.

Hi @ns292022 , I think below is the solution for you.

1. In the table you are not showing the datediff where it is 1, so i used the sample data provided by you and also and one entry for datediff 1 as below.

2. Please use this below calculated dax column for Name column - 

Name =

IF('Table (2)'[datediff]=1,"Last Week",

IF('Table (2)'[datediff]>1 && 'Table (2)'[datediff]<=4,"Last 4 Weeks",

IF('Table (2)'[datediff]>4 && 'Table (2)'[datediff]<=12,"Last 12 Weeks",

IF('Table (2)'[datediff]>12 && 'Table (2)'[datediff]<=52,"Last 52 Weeks",BLANK()

))))

3. in this just replace the table name and nothing else. this is the output I'm getting,

This will work for you.

Thanks for sharing this, however the output that I need should give the summation of last week and last 4 weeks values as CY, i;e Last week = 164, Last 4 Weeks = 164+304=468, as last 4 weeks also includes last week but with my approach as I have already tagged datediff 1 as Last Week it is excluding 1 from last 4 weeks. Here is the sample data

Hi @ns292022 ,

Correct , as you have tagged it has 1 it is showing separtely as last week. If you remove the last week condition and just keep >=1 and <=4,"Last 4 Weeks", it will work.

yes, but I have to show data separately for Last Week, Last 4 Weeks, Last 12 Weeks and Last 52 Weeks and thats where I am stuck badly.

Grouping with IF needs the the groups to be mutually exclusive. In your case, i would suggest to do it with measures. Try to create measures with the code below：

CYLW :=

CALCULATE (

    SUM(TableName[CY]),

    TableName[datediff] <=1

)

CY4W :=

CALCULATE (

    SUM(TableName[CY]),

    TableName[datediff] <=4

)

CY12W :=

CALCULATE (

    SUM(TableName[CY]),

    TableName[datediff] <=12

)

CY52W :=

CALCULATE (

    SUM(TableName[CY]),

    TableName[datediff] <=52

)

then try to plot the Table Visual with these measures.

Thanks for sharing this but in this way I have to create 4 diffrent measures for CY whereas I need the values in 1 column like this: 

here is the sample data 

I cannot change the output . Thanks!
