Thanks for trying :}

In the end I got it sorted with the following
select
dm.docnum,
dm.alias1,
dm.docname,
dm.alias2 as "Status",
dm2.alias2 as "Reply"
from docmaster as dm
left outer join
( select
alias1,
subclass_alias,
alias2,
entrywhen
from docmaster
where subclass_alias in ('Reply','MinTR')
and alias2 in ('PENDING','COMPLETED')
) as dm2
on dm2.alias1 = dm.alias1
where dm.subclass_alias='Post'
and alias2 in ('PENDING','REDRAFT');

Cheers,
Andrej
