How to get weekwise count

[saivina2920]

I have the below data. i want to get count of empno in y axis and get count weekwise of using EmpRelieve Date in x axis.

The below example shows E101A contains 3 records. we just want to eliminate like _MN and _DN, etc. we have to take only unique
value of E101A only not considering _MN like that.

So unique count of Emp No is : 5 (E101A,E102A,E103A,E104A,E105A) - Y-Axis
Weekwise count of EmpRelieve Date : (0-7, 8-14,15-21) - X-axis

How to create DAX expression and make the chart using x and y axis using the above...?

EmpNo	EmpRelieve Date
E101A	10/1/2022
E101A_MN	10/1/2022
E101A_MN	10/1/2022
E102A	15/03/2022
E103A	12/1/2022
E103A_MN	12/1/2022
E103A_MN	12/1/2022
E104A	25/11/2021
E105A	20/10/2021

Hi @saivina2920 , 

Here's my solution.

1.Create a calculated column to remove "_MN" and "_DN". 

EmpNo without MN/DN =

IF (

CONTAINSSTRING ( [EmpNo], "_MN" ) = TRUE ()

|| CONTAINSSTRING ( [EmpNo], "_DN" ) = TRUE (),

LEFT ( [EmpNo], LEN ( [EmpNo] ) - 3 ),

[EmpNo]

)

2.Create a calendar table. And sort the Year-Weeknum column by the sort column.

Calendar =

ADDCOLUMNS (

CALENDAR ( MIN ( 'Table'[EmpRelieve Date] ), MAX ( 'Table'[EmpRelieve Date] ) ),

"Year-WeekNum",

YEAR ( [Date] ) & "-"

& WEEKNUM ( [Date], 2 ),

"sort",

YEAR ( [Date] ) * 100

+ WEEKNUM ( [Date], 2 )

)

3.Create the following visual. Select "Count(Distinct)".

You can check more details from my attachment.

Hi,

If you want to build a simple aquick Date Table you can use CALENDARAUTO function, which scans your model to get the start and end date of your calendar.

I do agree with speedramps, it a good practice to use a date table and it brings you a lot of possibilities.

Hi saivina2920

It is bad pratice to start creating your own date logic using DAX. ☹️

It is best practice to create a calendar table in Power Query with a week column

using the Date.StartOfWeek comand.

Build a Calandar once and use it always for slicing or sub totalling by week, month or year. 😀😀😀
