2 Measures referencing 1 Dim but on different grains withe second measure having a 2 key collumns

Question

Hi, I need help please - I am stuck
I know how to add 2 measures on different grain but Meas1 joins on DimItem on lowest level but the Meas2
joins the DimItem on higher level combination of 2 collumns (key)
DimItem (level: itemcode -> class -> pack)
Meas1 (grain Itemcode) reference DimItem (itemcode)
Meas2 (grain class + pack) reference DimItem ????
I thought of creating a compositekey(class+pack) on both DimItem & Meas2 with Dim Compositekey type = regular (tried reference)
it just does not work, I want to when selecting class/pack both Measures return results
Please any help, im stuck and need to move forward

Hi,
Thanks for posting the CREATE TABLE and INSERT statements.
Don't forget to post the results you want given that sample data.
There's no problem outer-joining a table to 2 other tables when you use ANSI join syntax, like this:
SELECT    b.col6
,         a.col5
FROM             tablea  a
JOIN             tableb  b  ON   b.col1  = a.col1
                            AND  b.col2  = a.col2
                            AND  b.col3  = a.col3
LEFT OUTER JOIN  tablec  c  ON   c.col4  = a.col4
                            AND  c.col6  = b.col6
ORDER BY  b.col6
,         a.col5
Of course, there's no reason to include tablec at all if you're not going to use any of the data in it.
I recommend ANSI notation for all joins, especially outer joins.
