Days between dates row by row - Power query or DAX?

Hi 

 

I have a table withproperty ref, Job number, Job description, Supplier, Date logged. We have suppliers who carry out repairs at individual properties. Sometimes they will carry out more than one repair at the same property over time.

 

I would like either a power query solution or DAX function that check the property reference , job desctiption and supplier name.

If these appear more than once I would like to calculate the number of days from when the job was previously logged. Row by Row.

Some properties will have up to 10 jobs logged agains them. In this example there are 2 properties each one has a the same supplier who carried out 4 repairs. The last column is the result that I would expect

 

The example below is a snapshot of the table

@cottrera , Try a new column like

New column =

var _max = maxx(filter(Table, [Property Ref] = earlier([Property Ref]) && [Date Logged] < earlier( [Date Logged] ) ),[ [Date Logged] )
return
datediff([Date Logged],_max, day)
