Question

Hello,
I'm doing enhancement  to filter the data for the input parameters. Also I've coded implicit enhancement for the selection parameters to be displayed on standard IE05 selection screen.
Defined a block as follows in standard  program RIHEQUI20
selection selectio begin of block b1 with frame title text-099.
select-options:
                    cre_date for equi-zzcreate_date,
                    lp_pdate for equi-zzprint_date.
selection selectio end of block b1.
now to filter the data corresponding to the input in selection parameters i've explicit enhancement point in which added coded in where condition
as
zzcreate_date IN cre_date
AND zzprint_date IN lp_pdate
but error message showing the above heading
Solution for that....PLZ help!!

And for data to filter according to select-option , implemented an explicit enhancement in section.
code for that is in include miequi20
