Calculate Duration between phases from an Audits table

[rixmcx59]

Hello all, trying to find the best approach to get the duration of each Phase in the data below, I have an expression that's getting the duration from the audit dates but I need to use the createdonAccount date to get the first date. I need to calculate all durations, from when the customer was created in the accounts table, to the first change, second change, third change and so-on. then I need the final duration which is the last change until Now()

accounts.name	logicalName	createdonAccount	createdonAudits	OldPhase	NewPhase	Duration	Index
Customer A	audits_phase	2/13/2024 1:21	3/20/2024 17:27	NewCustomer	Phase 0		7865
Customer A	audits_phase	2/13/2024 1:21	3/21/2024 15:12	Phase 0	Phase 3	1	7986
Customer A	audits_phase	2/13/2024 1:21	4/3/2024 19:54	Phase 3	Phase 4	13	9961
Customer B	audits_phase	2/26/2024 18:24	2/26/2024 18:25	0	NewCustomer		1518
Customer B	audits_phase	2/26/2024 18:24	3/6/2024 17:53	NewCustomer	Phase 3	9	4611
Customer B	audits_phase	2/26/2024 18:24	3/14/2024 22:21	Phase 3	NewCustomer	8	6817
Customer B	audits_phase	2/26/2024 18:24	3/18/2024 16:50	NewCustomer	Phase 3	4	7337
Customer B	audits_phase	2/26/2024 18:24	3/27/2024 22:11	Phase 3	Phase 4	9	8964

The expression I am using now

Duration = 
VAR temp =
    TOPN (
        1,
        FILTER (
            audits,
            audits[accounts.name] = EARLIER ( audits[accounts.name]  )
                && audits[createdonAudits] < EARLIER ( audits[createdonAudits] )
        ),
        [createdonAudits], DESC
    )
RETURN
    DATEDIFF ( MINX ( temp, [createdonAudits] ), audits[createdonAudits], DAY )

Thanks for any help

Yes, for cutomer A, line 1, the first duration would be between the createdonAccount date 2/13/2024 and the earliest createdonAudit date 3/20/2024, so Customer A result shound have a start and end date for each Phase like below

New Customer To Phase 0 = 37 days  3/20/24 - 2/13/24

Phase 0 To Phase 3            = 1 day      3/21/24 - 3/20/24

Phase 3 To Phase 4            = 13 days   4/3/24 - 3/21/24

Phase 4 To Now()               =  Now() - 4/3/24

thanks for the resonse

Hello, after looking into the Audits data, there is a created date identified by a change type column, so now the the calculated column is working. I just need to figure out how to get the current duration, which is the days since the last change date and Now(), I'm guessing I need to add a calendar table and use todays date as the end date.

Thanks
