Calendar array to return unique results based on date and PO number
<p>I am trying to modify the below array to determine if a date and PO number have already been returned as a result for a date then skip to the next PO. see the attached screen capture which is returning the same PO number multiple times in the calendar.</p>

<p>I'm using named ranges (CalList, PO_Number) when referencing the table holding all the data.</p>

<p>=IFERROR(INDEX(CalList,SMALL(IF(Date=A$8,ROW(Date)),ROW(1:1))-TableRowStart,5),"")</p>

<p>In the screen capture "Garb" is showing up 3 times and "Stance" 5 times, and I'm looking for the array formula to determine that PO and Date has already been used in the calendar so skip to the next matching date and PO.
