Mass Additions Create - Initial Posting from A/P bringing prior years A/P activity into Assets Modul

 Hi-

We are in the implementation phase, and are testing the Mass Additions Create process from Accounts Payable.   When we kick off the initial Concurrent Request from A/P to bring the A/P activity, it brings over all the invoices posted to the defined Asset accounts from the beginning of time (2+yrs). There are a few open (recent months) periods open in A/P - -but it's bringing invoices from closed periods as well.

Have I set something up incorrectly?  Is there a way to just bring over only new/current period activity? 

Thank you-
