Hi,
Why you r writing so many select query's on KONV.
I think you can write the logic as follows
select kbetr kwert kschl from konv INTO CORRESPONDING FIELDS OF table it_konv
for all entries in IT_VBRK
where KNUMV = IT_VBRK-KNUMV
   and ( kschl eq 'ZRPR'
        or kschl eq 'ZFAB'
        or kschl eq 'ZRLB' ) .
loop at IT_VBRP.
read table IT_VBRK with key ebeln = IT_VBRP-VBELN.
if sy-subrc = 0.
loop at IT_KONV where knumv = IT_VBRK-KNUMV
sum the condition values
endloop.
endloop.
