APXIIMPT- Open Interface Import -- GL DATE in Closed Period

In Release 11.5..10.2

Is APXIIMPT suppose to mimic the functionality of the manually entering an invoice in the invoice workbench?  If the invoice date is in a closed period, the gl date is automatically made the first day of the first open period.  This is not happening when we use the Open Interface Import.  We get an error message.  The documentation (oracle payables user guide) says it should be in an open period.  I know R12 is suppose to move the date to the open period.

What is the current functionality for R11?

thanks
