checks in SM30

Hi All,

Hope are all doing fine!!!

am entering values in database table thru sm30 ( table maintenance) ,,,but while saving the entries in the database table..,i have to validate the entries for a particular fields ,,,

so am using select single ..........where fld1 = fld2 ....

fld2 is the value which am entering in the sm30,,,,but in the debugging mode i have checked that fld2 is not getting populated and its empty,,, i have even entered table-fld2 in the debugging mode but even its empty the value is not getting populated

Any solutions for this will be highly appreciated!!!!

Thanks

Jack
