Hi $wapnil
This is just a suggestion as i do the same thing,
Is your parameter feild your talking about a string?
If it is, go to the select expert>show formular>>> Formular Editor..
and change your statement
FROM
({Tablename.fieldname} = {?PARAMTER}
TO
({Tablename.fieldname} like {?PARAMTER}
Now when you refresh your report use the WILDCARD * FOR ALL
so REFRESH REPORT
Enter Parameter *
This will pass everything from the field to the paramter so you dont have to go through and select everything.
A step further,
You could then go to the PARAMETERfield righclick EDIT
And add the default value *
This defaults the field to '*' everything.
Hope that helps.
