Heena,

First of all, you might consider not selecting into a table. You might change your code to something like this:

sele cnt(id) as dup_chk from party_master into cursor temp where party_master.p_grp = control1.value and party_master.p_code = control2.value

IF dup_chk > 0
select party_master
=TABLEREVERT(.T.)
if eof()
skip -1
endif
thisform.refresh()
ENDIF

use in alias('temp')

Also, if you have your party_master table in the dataenvironment, be sure to set the buffermodeoverride property to something that will allow you to do buffering. If you're opening up the table in code, you'll have to go a few extra steps. Look at "set multilocks on" and "cursorsetprop" and "buffermodeoverride" for more detailed descriptions.
