Did Cognos resolve the screentip issue in Version 10?
In 8.4.1 screentips work in QS and RS, but not in AS..
nope
Populate screentip
Specifies whether the import uses the description field as a screenTip.
True allows the content of the description field to be seen as a screentip in IBM Cognos Report Studio, Query Studio or IBM Cognos Business Insight Advanced.
Looks like you need to raise and enhancement with IBM or get it pushed.
