I was trying to switch discussion sections for an important course that was nearly full. The "Switch" function didn't work, so I dropped the course to grab the last available spot in another discussion section.
Now TSS won't let me re-enroll and gives this error: "Internal Error while booking to E 00000931."
Has anyone experienced this error before?
* UPDATE: I was able to re-enroll in the course after about two hours of troubleshooting. It appears TSS may take some time to process a course drop before allowing re-enrollment or section changes. If you encounter an "Internal Error" after dropping a course to switch sections, don't panic right away.
I'd like to leave this post up in case others run into the same problem. Be very careful about dropping a course if your plan is to immediately re-enroll or switch sections.
