Yes DATEADD requires contiguous date selection

So you'll need a Calendar table and then reference the 'CalendarTable'[Date] Column

 

This should work as a COLUMN in your LEDGER table

tmpDateAdd  = LEDGER[InvoiceDate] + RELATED(TERMS[TermsDays])

    Thanks Sean, that's what I went with in the end (date+days), but was curious why it wasn't work.

     

    Hadn't occured to me that not using a separate calendar table, in this example, would cause me an issue - but lesson learnt!

    (I spend more time in SQL Server than I do PBI, and whilst using a calendar lookup table is just as important in that environment, in this particular scenario, it wouldn't have been an issue)

     

    Thanks for pointing me in the right direction though, much appreciated.
