How do we deactivate the grouping of REQ lines onto PO…

Req lines are still being grouped on the PO even though GROUPING_ALLOWED_FLAG is stet to "N,

per oracle docs   970800.1  and   756710.1   changing the GROUPING_ALLOWED_FLAG flag to "N" should allow separate PO lines to be created via Autocreate,

but combined PO lines are being create using the logic... combine number of units and apply the lower price/unit cost
