MINIMUM Order Date

[upwardD]

Hi,
I have a task to display a table with customers details and beside the first date the customer made orders, I am to create a measure that returns the next available date
I used the MIN (DATE) which is not correct. It should be simple but I am trying to master this language ASAP.
I am to only show the date where a customer made an order [Next Order Date ] beside the first order.

I want the report to show only the customers where Next Order Date is not blank
Thank you so very much.

Hi @UpwardD.

Here’s one way.

The DAX you have returns the minimum (first) order date.

First Order Date = MIN ( Orders[Order Date] )

To get the second order date, just get the minimum of those after the first order date.

Second Order Date = 
VAR _FirstOrderDate = MIN ( Orders[Order Date] )
VAR _SecondOrderDate = CALCULATE( MIN ( Orders[Order Date] ), Orders[Order Date] > _FirstOrderDate )
RETURN
_SecondOrderDate

Finally, to just show those customers with second order dates, you can use the filter pane.

Is something like this what you’re looking for?

Your original post doesn’t make it clear if you are looking for the next order date in the filtered period, or the next order date including and after the filtered period.

So, I have included both.

Step 1 - you were using a naked column reference in your original table, I changed that to a measure:

 Order Date Measure = 
FIRSTDATE( Orders[Order Date] )

Step 2 - the measure that respects the filter (will not show order dates after the filter period)

Next Order Date = 
VAR FirstOrder = 
    IF( Orders[Order Date Measure] = BLANK(), 
        FIRSTDATE( 'Date'[Date] ), 
        Orders[Order Date Measure] )
VAR NextOrder = 
    CALCULATE( 
        FIRSTDATE( Orders[Order Date] ),
            Orders[Order Date] > FirstOrder)
RETURN
    NextOrder

Step 3 - the measure that goes past the filter

Next Order Date (dates including and after filter) = 
VAR FirstOrder = FIRSTDATE( Orders[Order Date] )
VAR StartPeriod = 
    IF( FirstOrder = BLANK(), 
        FIRSTDATE( 'Date'[Date] ), 
        DATEADD( FirstOrder, 1, DAY ) )
VAR EndPeriod= LASTDATE( ALL( 'Date'[Date] ))
VAR NextOrder = 
    CALCULATE( 
        FIRSTDATE( Orders[Order Date] ),
            DATESBETWEEN( 'Date'[Date], 
                StartPeriod,
                EndPeriod))

RETURN
    NextOrder

NOTE: this actually builds on the solution provided to you by @Rens in this post:

Days Between First and Last Purchase

Hi upwardD, Good question. Find a possible solution attached. One note: You ask the difference between first purchase and last purchase in the first part of question, but then ask the difference between first purchase and next purchase further down. I assumed you meant first and last purchase date, so that is what I implemented. Days_Between 1st_and_Last_Purchase.pbix (221.6 KB)

It errored out on the server.

Thank you

@Heather

Next Order Date = 
VAR FirstOrder = 
    IF( Orders[Order Date Measure] = BLANK(), 
        FIRSTDATE( 'Date'[Date] ), 
        Orders[Order Date Measure] )
VAR NextOrder = 
    CALCULATE( 
        FIRSTDATE( Orders[Order Date] ),
            Orders[Order Date] > FirstOrder)
RETURN
    NextOrder

Hi @Heather,
Thanks for the reply. I did applied the steps that @Rens gave. We were never able to run it against the server. It timed out everytime I try to work with it. Even now, the Next Order Date produce the same resukt for all the rows:

Thank you so very much. I anticipate your reply.

Hi @upwardD. It runs fine on my machine … I wouldn’t have posted it otherwise. Can you reboot, just launch Power BI Desktop, and try again? (I’d like to check if it might be a memory issue on your machine …).

@upwardD,

I did not have any problems with my solution either - and as you can see, the solutions provided by @Greg and I are very similar.

What version of Desktop are you using @upwardD ?
I noticed in your original demo model that you weren’t using a measure for the “first date” value - do you have any measures that are working?

[upwardD]

Hi @Heather, thanks for getting back. I am using the latest version of Power BI desktop. I got not run it on a test server either. I had to put the logic into SQL to overcome the issue.
Thank you so much for your support.

[Heather]

I’m glad you found a solution - but you may want (as you have time) to go over your model again for performance improvements.

It seems that there might be some other issues with your model if this measure is not working.
