Workaround for Creating Views with UNION

I need to implement the following SELECT statement as a view, however, IDS = 7.23 does not allow unions on views. (IDS 7.3 does): SELECT 1, 0, maintent.mtnoi, sparepart.spptoi FROM mc.maintent, mc.sparepart WHERE maintent.splst_oi =3D sparepart.splst_oi AND maintent.splst_oi IS NOT NULL AND sparepart.ppl_oi IS NULL UNION ALL SELECT 2, 0, maintent.mtnoi, sparepart_1.spptoi FROM mc.maintent, mc.sparepart, mc.sparepart sparepart_1 WHERE maintent.splst_oi =3D sparepart.splst_oi AND sparepart.ppl_oi =3D sparepart_1.splst_oi AND maintent.splst_oi IS NOT NULL AND sparepart.ppl_oi IS NOT NULL AND sparepart_1.ppl_oi IS NULL; = Thanks.
