Absolutely clear as mud :P

I think this might be what you're after

SELECT       docnum,       alias1,       alias2,       subclass_alias
FROM       docmaster
WHERE       subclass_alias = 'Inquiry'   AND alias1        IN       (               SELECT                       alias1
             FROM                       docmaster               WHERE                       subclass_alias = 'Reply'
              AND                       (                               alias2 = 'Pending'
ORalias2 = 'Redraft'                       )       )
