As per below on date 02/01/2025 I want alert of"A" considered as only 1 and remove duplicates from same col. Same on date 02/02/2025 alert of "A" should be considered count only 1 and remove duplicates. How can this be done ?

Hi @Manasi25 ,

Refer to the steps below. In PowerQuery, first sort by the number column, and then select the Alert column and Date column to remove duplicates.

@Manasi25 Try creating a new table as below:

NewTable = SUMMARIZE('Table','Table'[Alert],'Table'[Date],"Count of Alert", DISTINCTCOUNT('Table'[Alert]))

@Manasi25 Create a new table that summarizes the data by "Alert" and "Date":

DAX

SummaryTable =

SUMMARIZE(

    'YourTable',

    'YourTable'[Date],

    'YourTable'[Alert],

    "AlertCount", COUNTROWS('YourTable')

)

[Manasi25]

I created table with only on column. and its giving me below error.

[bhanu_gautam]

SummaryTable =

SUMMARIZE(

    'Table',

    'Table'[Date],

    'Table'[Alert],

    "AlertCount", COUNTROWS('Table')

)

Please find the PBIX with solution

Okay, thats fine, what if I want to remove all duplicates and keep row of the alert which alerted first by date and time.

@Manasi25 

Add a calculated column to rank the alerts by date and time:
AlertRank =
RANKX(
FILTER(
'YourTable',
'YourTable'[Date] = EARLIER('YourTable'[Date]) &&
'YourTable'[Alert] = EARLIER('YourTable'[Alert])
),
'YourTable'[Time], // Assuming you have a 'Time' column
,

Create a new table that keeps only the first occurrence of each alert per day:
FirstAlertTable =
FILTER(
'YourTable',
'YourTable'[AlertRank] = 1
)
This approach uses the RANKX function to rank the alerts by date and time, and then filters the table to keep only the first occurrence of each alert per day. If you do not have a time column, you can rank by the date alone.

It doesn't make any difference with my actual data. I want to keep row from "Alert" col by day.

Want to remove duplicates. Keep the only one alert which has 5 duplicates entry in a day. Same for another could happen, but want entry only 1 for each day.

Hi @Manasi25 

You could select the 3 columns and click Home>Remove Rows > Remove duplicates. This will allow you to remove the duplicates and count as 1 for similar alerts.

Hope this helps. Do give a kudos if it works!
