PI17769: DYNAMIC CUBES - CROSSJOINS IN VIRTUAL CUBES NOT HANDLED EFFICIENTLY WHEN SUPPRESSING NULLS

APAR status

• Closed as program error.

Error description

• When a crossjoin is implemented to create a Virtual Cube with
  null suppression on the source cubes, the SQL generated doesn't
  suppress nulls until all of the relevant data has been processed
  from both source cubes.  This is very inefficient.  Nulls should
  be suppressed on the source cubes before bringing the data back
  to be crossjoined.??
