you using Mondrian version 3 or 4?
Mondrian 4 supports composite
keys. Define a composite primary
key for the dimension table, and
include multiple columns in the
ForeignKeyLink.

<div>See <a moz-do-not-send="true"

<div>Neither version of Mondrian
supports left join. Can you
describe what you hope would
happen? If a record in the
“sales" fact table has a
“productId” value that doesn’t
exist in the “product" table,
would you expect that that fact
to be counted against a “null”
member of the [Product]
hierarchy? Each hierarchy has a
null member, but the system
removes them from axes. So you’d
need a user-defined “other”
member.</div>
