I was supposed to get off at noon, but I decided to do some prep work for my TMAP upgrade and ran into two separate problem that wasted the whole afternoon.
One of the problems was caused by moi (yep I made a mistake) when building the stack files and selected the wrong Solaris platform. Wasted a lot of time on fixing that.
The other problem: I got an SNC error from installer.
Found a workaround by telling the installer SNC_ENABLED = 0. Don't ask me. It's SAP.
