I think that Joe wanted to see the CREATE TABLE DDL for tables
tblstockawal and tbltransaksi.
If you "SELECT * FROM public.vwtest" does the query return expected
data?
If any of these columns contain null (tblstockawal.qty,
tbltransaksi.masuk, tbltransaksi.keluar) then the result of any SUM is
null. This means that vwtest.onhand will be null.

CREATE OR REPLACE VIEW public.vwtest (
produkid,
warehouseid,
onhand)
AS
SELECT dt.produkid,
dt.warehouseid,
sum(dt.awal + dt.ttlmsk - dt.ttlklr) AS onhand
FROM (
SELECT tblstockawal.kodebarang AS produkid,
tblstockawal.warehouseid,
sum(tblstockawal.qty) AS awal,
0 AS ttlmsk,
0 AS ttlklr
FROM tblstockawal
GROUP BY tblstockawal.kodebarang, tblstockawal.warehouseid
UNION
SELECT tbltransaksi.kodebarang AS produkid,
tbltransaksi.warehouseid,
0 AS awal,
sum(tbltransaksi.masuk) AS ttlmsk,
sum(tbltransaksi.keluar) AS ttlklr
FROM tbltransaksi
GROUP BY tbltransaksi.kodebarang, tbltransaksi.warehouseid
) dt
GROUP BY dt.produkid, dt.warehouseid;
