Missing SAP standard indexes (including unique and clustered indexes)
Customer-created indexes not meeting the SAP standard (that is, not
defined as data dictionary extension indexes)
SAP standard indexes based on a former BW release if they are different
to the standard of the current BW release.
Indexes that exist on the database only (without data dictionary
