Hi Sathish,
Last weekend I've tried to update explorer and faced same issue.
A column name changed on from OBJECT_SUFFIX to OBJECT_TYPE_ID on HANA views ACTIVE_OBJECT and ACTIVE_OBJECT_TEXT_CONTENT.
This provoke the script on SAP Note 1799606 became wrong for SP06. I adjusted it to work on SP06, the steps are still the same from SAP Note.
