Can the sumproduct formula be modified to return text? Here is my formula:
AM5 = part number
BOM!AM5:AM300 = list of part numbers (unsorted random data)
BOM!AN5:AN300 = list of part names
=SUMPRODUCT(--(AM5=BOM!AM5:AM300),BOM!AN5:AN300)
returns 0
=SUMPRODUCT(--(AM5=BOM!AM5:AM300))
returns 1 verifying there is only 1 match...
AM5 = part number
BOM!AM5:AM300 = list of part numbers (unsorted random data)
BOM!AN5:AN300 = list of part names
=SUMPRODUCT(--(AM5=BOM!AM5:AM300),BOM!AN5:AN300)
returns 0
=SUMPRODUCT(--(AM5=BOM!AM5:AM300))
returns 1 verifying there is only 1 match...
