Information about non invoiced order lines

 Hi,

      I need to get the report for the customer with specification as Total Fully allocated / On PPS. For the Fully allocated order lines I am considering the picked qty and shipped qty but not invoiced. But determining the order lines which are not yet invoiced the only option i see is the checking the existance of order lines info in ra_customer_trx_lines_all(As there might be chances when the delivery detail with released status 'I', the line might be interfaced and invoice generated). Is this assumption correct or any other way we can determine this.
