Calculating duration between two dates in different rows based on duplicate value

[Anonymous]

Hi, I want to calculate the duration (# of days) between two fields based on the same value.

For example, I have data:

Case_ID	Created Date	Sent Date	Account_ID	Duplicates
303	3/1/2020	3/16/2020	4123596	0
325	3/2/2020	3/13/2020	3800302	0
328	2/1/2020	3/2/2020	3451087	0
335	2/12/2020	3/3/2020	4083696	0
336	3/1/2020	3/11/2020	3320916	0
337	2/8/2020	3/17/2020	1183546	0
340	2/9/2020	3/9/2020	3797473	0
341	2/10/2020	3/3/2020	2921660	0
344	2/11/2020	3/3/2020	1105487	0
349	2/12/2020	3/25/2020	184470	0
350	2/13/2020	3/16/2020	2134153	0
354	2/14/2020	3/2/2020	3804859	0
355	2/15/2020	3/3/2020	2699155	0
356	2/16/2020	3/3/2020	2650462	0
357	2/17/2020	3/16/2020	2658859	0
358	2/18/2020	3/12/2020	2827333	0
363	2/19/2020	3/23/2020	3081094	0
366	2/20/2020	3/20/2020	3056638	0
347	2/21/2020	3/2/2020	3788646	0
360	2/22/2020	3/4/2020	3209903	0
364	2/23/2020	3/20/2020	3797230	0
368	2/24/2020	3/30/2020	3198190	0
362	2/25/2020	3/18/2020	3294749	1
361	3/22/2020	3/28/2020	3294749	1
367	2/27/2020	3/19/2020	3148921	1
369	3/22/2020	3/28/2020	3148921	1

The duplicates show that there are two different cases for the same account. I would like to find out if the account is the same then what is the duration between when the case was created on the second case - report sent date for the first case. The order will be based on the created date. The goal is to understand if the same account is coming back to create another case within 90 days of when their report was sent.

For example:

Account 3294749

1st Case = 362 (created on 2/25, report sent 3/18/2020)

2nd Case = 361 (created on 3/22, report sent 3/28/2020)

Expected Outcome (new column):

361 Created Date - 362 Report Sent Date = 4 days

Thank you!

There is an example of the workday in this file. Please take distinct count of date where workday =1

This calculated column will do the trick:

Date Difference =
VAR CurrentAccount = [Account_ID]
VAR CurrentRecordSet =
    FILTER(
        'DateDiff Table',
        'DateDiff Table'[Account_ID] = CurrentAccount
    )
VAR AccountCount =
    COUNTX(
        CurrentRecordSet,
        'DateDiff Table'[Account_ID]
    )
VAR CreatedDate =
    IF(
        AccountCount > 1,
        MAXX(
            CurrentRecordSet,
            'DateDiff Table'[Created Date]
        ),
        0
    )
VAR SentDate =
    IF(
        AccountCount > 1,
        MINX(
            CurrentRecordSet,
            'DateDiff Table'[Sent Date]
        ),
        0
    )
VAR DateDifference =
    DATEDIFF(
        SentDate,
        CreatedDate,
        DAY
    )
RETURN
    DateDifference

It returns zero if there is only one record for an account.

If you want it to return the dates between sent and created even if there is only one record, get rid of the IF() function. So for example:

VAR SentDate =
    IF(
        AccountCount > 1,
        MINX(
            CurrentRecordSet,
            'DateDiff Table'[Sent Date]
        ),
        0
    )

becomes

VAR SentDate =
        MINX(
            CurrentRecordSet,
            'DateDiff Table'[Sent Date]
        )

Same logic for the CreatedDate variable. You didn't specify in your OP, so wasn't sure how you wanted those handled.

Hi @edhans ! Thank you for your reply, your column has exactly what I am looking for. I'm not sure why I am getting the 'Token Eof Expected' error where the CurrentAccount expression is. Any thoughts?

VAR CurrentAccount = [Account_ID]

Here are the data types that I am using:

Case_ID = Text

Account_ID = Text

Sent Date = Date

Report Date = Date

Thank you again!

Jenny

@Anonymous I'd need to see a screenshot of the error. If you are entereing this as a calculated column, it should work. THat syntax will not work as a measure.

@Anonymous , See if this can help

Working Days = CALCULATE(DISTINCTCOUNT('Date'[Working date]),VALUES(Sheet1),filter(all('Date'),'Date'[Date]>=[Min Created Date] && 'Date'[Date] <=[Max Send date]),NOT(ISBLANK('Date'[Working date])))
