How to apply security rules on Payables Open Interface Import

Hi,

How do I make the "Payables Open Interface Import" program apply the security rules in AP?

For example, I wanted to have the "Payables Open Interface Import program" reject an invoice with one of the segments in its GL Account flexfield is not valid per a security rule.  How may I do that? 

I found that our Payables Open Interface Import program ignores our AP security rules, allowing iinvoice to be loaded into the AP invoice tables without errors when its distribution lines have a Segment1 value in the GL account that is not included in the values allowable by the security rule for the Operating unit the invoice was loaded into.
