SOP transaction import with failed line items

Hello,

We are using Integration Manager to import SOP orders. How can we configure IM to import the order with partial line items in situations where there are failed line items on the same order. For instance, if I have an order with 20 line items and one fails, the entire order is cancelled from import. I 'd like for IM to import the order with the 19 line items. Is this possible to do?
