Dax calculations to display two dates from one date column, and the time difference between the two.

[Anonymous]

Hello all, 

I need your help to improve on some Dax functions I have. I have the following sample data related to tickets treated during week number 15 of the month of April 2023, I would like to display the received and sent dates based on the Date of Action column (and only display the dates related to week number 15 of April, I have created a relationship btw between the date table and Date of Action column, but some outputs are still not correct), then calculate the time difference between the two (if the result is zero then it is understood that the ticket treatment was achieved in less than a day). 


I have implemented the following DAX calculations to get the results I have shown in the Power report below

PERSON_TIMELINE = RANKX(FILTER(WEEKLY_IDs, WEEKLY_IDs[Ticket_Nb] = EARLIER(WEEKLY_IDs[Ticket_Nb]) && WEEKLY_IDs[Sender_Name] = EARLIER(WEEKLY_IDs[Sender_Name])), WEEKLY_IDs[Date_of_Action], , ASC, Dense)

TICKET_TIMELINE = RANKX(FILTER(WEEKLY_IDs, WEEKLY_IDs[Ticket_Nb] = EARLIER(WEEKLY_IDs[Ticket_Nb])),WEEKLY_IDs[Date_of_Action], , ASC, Dense)

From the above calculations, I created the three columns shown in the Power BI report below:

RECEIVED_DATE = CALCULATE(MIN(WEEKLY_IDs[Date_of_Action]), ALLEXCEPT(WEEKLY_IDs, WEEKLY_IDs[Ticket_Nb]), WEEKLY_IDs[TICKET_TIMELINE]=WEEKLY_IDs[PERSON_TIMELINE]) 

REPLY_DATE =

IF(

    ISBLANK(CALCULATE(MIN(WEEKLY_IDs[Date_of_Action]), ALLEXCEPT(WEEKLY_IDs, WEEKLY_IDs[Ticket_Nb]), WEEKLY_IDs[TICKET_TIMELINE] > WEEKLY_IDs[PERSON_TIMELINE])),

    WEEKLY_IDs[RECEIVED_DATE],

    CALCULATE(MIN(WEEKLY_IDs[Date_of_Action]), ALLEXCEPT(WEEKLY_IDs, WEEKLY_IDs[Ticket_Nb]), WEEKLY_IDs[TICKET_TIMELINE] > WEEKLY_IDs[PERSON_TIMELINE])

)

 

Treatment Duration = if(INT([REPLY_DATE])-INT([RECEIVED_DATE]) <= 0,0,

    INT([REPLY_DATE]) - INT([RECEIVED_DATE]))

Hello Jack,

Can you please share your pbix?

I'm also mildly confused on what your actual issue is. Can you be more specific? From what I gather, some Date Received values are not calculating correctly?
