Dear Tshering,
Would check whether you migrated to new statistics service with
checking followings.
1. nameserver.ini / [statisticsserver] / active = true
2. select value from _SYS_STATISTICS.STATISTICS_PROPERTIES where key =
'internal.installation.state';
-> the out of the SQL will be done (okay), if new statisticsserver
successfully installed.
Also Check the below notes.
1925684 - ABAP adjustments for SAP HANA SPS 7
1917938 - Migration of the statistics server for Revision 74 or higher
Please watch this video. http://www.saphana.com/docs/DOC-4403 . Hope this video will help you to understand more about new statistics server.
Best Regards,
Keerthan
