IN the above scenario for a po_nbr we have some receipts and each receipt have multiple ReceiptDtls and some ReceiptDtls have same receipt_nbr the problem is if receipt_nbr is same we have to take the last receipt_date how can we do that



Here we have receipt_nbr=26 but the receipt_date is diff we need to take 1979 not 1978 how to do that
