Order Import program fails to import line information

Hi,

Order Import program fails to import line information and the order header is created without line information. When the same record is imported through corrections form it imports the line successfully. With step by step process i observed that oe_lines_iface_all is populated with org_id when validation happens in corrections form, but the same is not populated when imported through order Import program (Passed operating unit in the parameters). Not sure if this is the cause. Any pointer towards this will be highly appreciated.

Thanks

Ramesh
