Inner join with data also from non having join column

Question

I have an Dim table which has to be joined with Fact Table using inner join, but also display the Dimension value " MasterGroup " inspite of data present or not in the fact table.
My Query:  .. This is an part of my stored procedure with more tables
SELECT a.SalesAmount, b.HeaderGroup ,c.CityName
FROM dbo.FactItem a
inner join dbo.[DimHeader] b
on a.sid = b.sid
left join dbo.DimCity c
on a.cityid = c.id
My DimHeader Table will have data like
MasterGroup
ChildGroup
etc...
which is an attribute.
There might not be any relevent fact data, but still i want the dimension data to display the "MasterGroup"

hello ,
usually this is not possible when the column you want to display when the matches not found from a table having a distinct values which are hard to declared static..
you can incorporate something like this if you cant change the join type ..
select distinct HeaderGroup from dbo.[DimHeader] tbl_outerleft join (SELECT a.sid,a.SalesAmount, b.HeaderGroup ,c.CityName
FROM dbo.FactItem a
inner join dbo.[DimHeader] b
on a.sid = b.sid
left join dbo.DimCity c
on a.cityid = c.id) tbl_Main on tbl_Main.sid =tbl_outer.sid
