You could do something like this:
rule 'empty documents'
...
when
$emptyDocs: List(size>0) from collect ( Document( field1== null || == (
"" ) , field2 == null || == ( "") ) )
then
//insert an error
Error fact0 = new Error();
fact0.setErrorCode( "code1" );
insert(fact0 );
//retract empty documents
for (int i=0; i < $emptyDocs.size(); i++){
retract( $emptyDocs.get(i));
}
end
