PO Import: System overwrite accrue on receipt flag for inventory items ...

I'm using the PO Import for adding additional purchase lines to an existing PO.

I fill PO_LINES_INTERFACE, PO_DISTRIBUTIONS_INTERFACE and PO_LINE_LOCATIONS_INTERFACE.

I'm importing both lines without internal items (no item id) and with. If I don't have an item id I don't fill the PO_LINE_LOCATIONS_INTERFACE and I set destination_type_code to EXPENSE in the distribution interface.

Now for inventory items I also want to import them as expense. So I set destination_type to EXPENSE and in the line location flag is set Accrue On Receipt Flag to No because that is what I've set in my system parameters.
