runtime error

hi

i am developing a report and when i execute it gives me runtime error.

the runtime error is:Error in the module RSQL accessing the database interface.

and it shows the the error line which i have written and it is like this.

select * from zfiexpartf into corresponding fields of table it_partp

where zzvencode in s_vcode and zzp_fxcyr in r_year and

zzp_fxcqtr in r_qtr.

give me an advice so as to what to do .

thanks in advance.

jacob.
