Clarity Release 16.0.3 Advanced Reporting
As part of DE63862 the materizalized view "dwh_sec_inv_inst_security_mv" was introduced to address performance issues noticed for DWH queries which were using DWH security views DWH_INV_SECURITY_V and DWH_INV_RESOURCE_V.
For the time being SAAS operations rolled back the security view definitions for DWH_INV_SECURITY_V and DWH_INV_RESOURCE_V to the original version.
DE66648 is created to populate the MV from the Load DWH Access rights job.
