Hi,
Do not put SELECT statements in a LOOP.
Try using FOR ALL ENTRIES along with the table.
select sum( WKGBTR )
perio
from coep into table IT_COEP1 FOR ALL ENTRIES in it_aufk1 where objnr EQ IT_AUFK1-objnr
and gjahr = p_gjahr
and kokrs = p_kokrs
and beknz <> 'A' and beknz <> 'L'
group by coepobjnr coepperio.
some mathematial operations.
num = p_gjahr - 1.
SELECT
SUM( WKGBTR )
INTO TABLE IT_COEP2
FROM COEP
FOR ALL ENTRIES IN IT_AUFK1
where objnr eq IT_AUFK1-objnr
and beknz <> 'A' and beknz <> 'L'
and gjahr eq num .
