help in the abap code

select distinct jhaga_{inserent jhaga}regulierer jhaga~avm_nr

jhaga_{ref_vbeln jhak}knumv into

corresponding fields of table bodyitab

from jhaga inner join jhak on jhaga~avm_nr =

jhak_{avm_nr where jhaga}inserent = p_advnum and

jhaga~fakdatum in r_datum.

write: 'the query is working'.

select knumv kschl kbetr kwert

from konv

into table cdata

for all entries in bodyitab

where konv~knumv = bodyitab-knumv.

I am getting the error in this line.....

loop at cdata into wac where knumv = bodyitab-knumv.

It is not comparing the condition out here.

Thanks in advance.
