Shaofeng SHI commented on KYLIN-849:
------------------------------------
This is a bug; The lookup table's PK can be derived from fact table's FK, which
is on the cube dimension columns in this case, so Kylin should be capabile to
fulfill this query; It has been fixed and committed in 0.7-staging and 0.8
branches;
> Couldn't query metrics on lookup table PK
