Created a new combo box (unbound) with 3 columns "ponumbe/productid/quantity", it autofills other fields on selection.
There are duplicate entries in combo box eg: same ponumber and different productid
PO Number Product id
45000123 10001
45000123 10002
combo box displays ponumber in ascending order, system always select the first ponumber, not able to select the 2nd ponumber with productid 10002
TIA
