Hey,
I am having trouble figuring out what appears to be a fairly simple report. Any help would be appreciated.
I have a Sales table containing 3 different batches of delivery tickets. The Tickets are listed consecutively and should add an increment of 1 to each ticket number.
The object of the report is to identify increments greater than 1 and thus determine missing tickets.
If someone could help with the DAX to determine the differences that would be great.
I also have included a ‘Row Rank’ column (Index) that resets whenever the Batch number changes. This is so when the Rank is 1, the first Difference value will be zero as seen in the table.
There are only Sales and Date tables in this data.
I know there are multiple topics on this subject already but most of them are much more complex than this or I couldn’t get them to work.
Thanks for your time.

Here's what i've got for the dax:
Diff =
var previousTicket = CALCULATE(MAX('Table'[Ticket]), ALL('Table'[Ticket]), 'Table'[Ticket] < SELECTEDVALUE('Table'[Ticket]))
var previous = IF(ISBLANK(previousTicket), SELECTEDVALUE('Table'[Ticket]), previousTicket)
return CALCULATE(SUM('Table'[Ticket]) - previous)
Here is a link to the report I need help with. It is in OneDrive.
Below is a screenshot of the report. It is intended to identify missing invoices. The first invoice in a Batch should be a zero in the 'Diff' column and subseqent invoices should be the difference between an Invoice number and the previous Invoice number. Normally the difference should be 1 unless there are missing invoices. You can see in the below screenshot the first two batches are working perfectly and then it breaksdown. The Measure's DAX is below.
Hi Vicky,
Here is a screenshot of my real world data. I have substituted 'History'[HIST_REF_NO] for 'Table'[Ticket] in your script. As you can see, the calculation starts out fine but soon goes off the rails. I wonder if you see what the issue might be. Thanks for your help.
