Answer 1

You could use an insert-select

INSERT INTO SAP_Mat_StoreBGA_test (BGA.Material, BGA.Component, SMT_Assembly)
SELECT BGA.Material, BGA.Component, SMT_Assembly FROM SAP_Mat_StoreBGA BGA 
LEFT JOIN SAP_Mes_BuildPlan ON SAP_Mes_BuildPlan.SMT_Assembly = BGA.Component
WHERE BGA.Component like '73%'
