Days Difference between work order previous open date and last work order closed date

[SAU1111]

Hi All,

I have a query as i have a table where i wish to create a difference between the same serial number's first Work order closed and second Work order opened date as Days Diff so that i can find out when the next work order was created after the previous one was closed . Please support .  Below is the list of details.  i have lots of serial numbers and Work order none in a sequence but randoms.

Hi @SAU1111 ,

Please add an index column in Power Query:

Then please try following DAX:

Days difference = 
var cur_index = 'Table'[Index]
var pre_index = cur_index+1
var diffe = CALCULATE(
    MAX('Table'[CreateDate]),
    FILTER('Table','Table'[Index] = pre_index && 'Table'[Serial Number] = EARLIER('Table'[Serial Number])))
return
DATEDIFF([ClosedOn],diffe,DAY)

If I misunderstand your demands, please feel free to contact us in time.

Best regards,

@SAU1111 , a new column

 Datediff( [Close Date], Minx(filter(Table, [Serial Number]= earlier([Searial Number]) && [Open Date] > earlier([Close date]) ) , [Open Date]) , Day)

or

Datediff( [Close Date], Minx(filter(Table, [Serial Number]= earlier([Searial Number]) && [Open Date] > earlier([Open date]) ) , [Open Date]) , Day)
