Millersville's database team resolved this problem on Thursday, 11 December 2014. New course shells are being created in D2L.
A glitch in the process Banner uses to send course shell creation information to D2L had been blocking the transfer of details about Spring 2015 courses. Banner tried to send the information, but D2L never received it, and this stopped the creation of Spring 2015 D2L shells for a time.
Millersville's database team made adjustments to the Banner-to-D2L update process to eliminate the glitch. Therefore, since Thursday, 11 December 2014, new course shells are once again being created in D2L.
