Hi All.
Just throwing up a fix to a bug. Reference APR is PM03061
If you want to hide the Views in the navigation pane of TM1Web IBM has this document to fix this.
https://www.ibm.com/support/knowledgecenter/en/SS9RXT_10.2.2/com.ibm.swg.ba.cognos.tm1_wb.10.2.2.doc/t_displayingorhidingtheviewsnodeinthenavigationpane_n510f6.html
How ever this does not work. This is a known bug. Upgrading doesn't help.
Simply instead of putting a N in the field. Don't put anything.
i.e.
<add key="NavTreeDisplayServerView" value="" />
This has worked for us.
