Values not loaded during import in Supplier and Supplier Sites

 Hi all, Need help.
I m using supplier open interfaces for loading supplier and their sites(sqlldr).
But the problem is i successfully loaded the data to the ap_suppliers_int and succesfully imported it with no errors encountered..
but then when i checked each data that i had loaded, found out that there were some constant values not loaded,

auto_tax_calc_flag
amount_includes_tax_flag

same problem in ap_supplier_sites_int..
I badly need responses for this problem..
we will be going oracle live next week:-(


Thanks in advance.
Miss lei
