Need to add serial number based on the date

[Santhosh_V]

Hi All,

I've 200+ rows of call history data and It will have multiple entries for each day for each users. I would like to add the serial number accordingly to start date to use it on a slicer. Below is the screenshot fo the data,

If start date is 2023-01-04, then serial number would be 1,

if start date is 2023-01-05, then serial number would be 2....

Any help on this would be appreciated.

Thank you.

hi @Santhosh_V 

try to add a column like:

Serial Number  =
INT( 
    DATE(
        LEFT([StartDateTime], 4), 
        MID([StartDateTime], 6, 2),
        MID([StartDateTime], 9, 2)  
    ) -
    DATE(2023, 1 ,4) +1
)

Hi , @Santhosh_V 

According to your description, you want to add a rank column from the "Date/Time" column (just compare the date not the time).

Here are the steps you can refer to :
(1)This is my test data:

(2)We can click "New Column" and enter this:

Column = RANKX('Table',DATEVALUE( FORMAT('Table'[Date],"yyyy-mm-dd")),,ASC,Dense)

(3)Then we can meet your need:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!

Hi @FreemanZ,

Thanks for your response.

May i know whether will this work if date value has changed?

Because the start date will get varied on monthly basis..

Thank you.
