What can I do when "Approve" or "Reject" does not work for a calculated plan?
Open Internet Information Services (IIS) and navigate to Sites > SciMoCa.
Change Status for Windows Authentication to Enabled:
Restart the SciMoCa website (Right click on SciMoCa > Manage Website > Restart):
Refresh the web interface of SciMoCa in your browser and try again to "Approve" or "Reject". Everything should work again as intended.
