Hi,
About miss some inforamation or Showing N/A status in Report.
It's means that some result events are either not saved in Administration Server database, were deleted or are saved less number of days than events about found viruses. Please see in detail here;
http://support.kaspersky.com/faq/?qid=208279573 You can see which events are saved on the Administration Server in the policy of the anti-virus application on the Events tab (select the necessary event and click the Properties button). Once you have enabled to store events on the Administration Server do not forget to “lock” the policy.
Kaspersky AdminKit older version has some problem with Report!
Please may try using the newer version of Kaspersky administration kit (1710). Good Luck.
