Column to indicate if same invoice has an earlier date

Anonymous — Thu, 07 Mar 2024 15:26:56 GMT

I have a data set in which I have a series of invioces with various criteria. But i'm trying to account for an issue in which multiple invoices are created for the same account. This would only occur if another criteria is met, in this case a flag is indicated...so I can't use Group By in Power Query

Can I create column in the table that would identify if that same accountID has another row with an earlier invoice date?

Hi Anonymous ,

I create a table as you mentioned.

Then I create a new calculated column.

Column = VAR _minDate = CALCULATE ( MIN ( 'Table'[Date] ), FILTER ( ALLSELECTED ( 'Table' ), 'Table'[accountID] = EARLIER ( 'Table'[accountID] ) ) ) VAR _maxDate = MAXX ( FILTER ( ALLSELECTED ( 'Table' ), 'Table'[accountID] = EARLIER ( 'Table'[accountID] ) ), 'Table'[Date] ) RETURN IF ( 'Table'[Date] = _minDate && 'Table'[Date] <> _maxDate, 1 )

Finally you will get the date you want.

Best Regards
