Can I use Oracle tools such as DBMS_STATS instead of BRCONNECT for regular statistic creation?
The Oracle package DBMS_STATS provides numerous options for automatically updating obsolete statistics (for example, GATHER STALE, GATHER AUTO), that can be executed periodically based on the Oracle job system. SAP does not support periodic creation of statistics for R/3 using these Oracle mechanisms (refer to Note 105047). Instead, you should always use BRCONNECT.
