Days between two dates in different rows
Hi everyone,
I've got a table that contains the price list of some products that my company buys from a certain supplier:
For each item there are the start date and the end date of the price shown in the line (31/12/2099 means the the price is currently valid).
My goal is to find out if there are any gaps between dates, so I need to calculate, for each item, the difference between the ValidityEndingDate and the next ValidityStartingDate:
Here is the PBIX file: https://www.dropbox.com/s/3q2rldzekcbjsh3/Days%20between%20dates.pbix?dl=0
I hope it's all clear. Thank you.
A calculated column in DAX:
ColumnZ = var _item = 'Table'[Item] var _endDate = 'Table'[ValidityEndingDate] RETURN CALCULATE(MIN('Table'[ValidityStartingDate]), FILTER('Table', 'Table'[Item] = _item && 'Table'[ValidityStartingDate] > _endDate))You can then use DATEDIFF in another column to get the days between the column and the ending date.
I haven't really tested it so please do that.

That's great HotChilli ! I've created this column:
Days between pricelists =var _item = 'Table'[Item]var _endDate = 'Table'[ValidityEndingDate]var _next_date = CALCULATE(MIN('Table'[ValidityStartingDate]), FILTER('Table', 'Table'[Item] = _item && 'Table'[ValidityStartingDate] >= _endDate))RETURN DATEDIFF('Table'[ValidityEndingDate], _next_date, DAY)
