On December 31 Control-M did not order jobs that were based on the CTMCALAL calendar. We prepared this calendar to contain all days but unfortunately December 31 was missing. But if you look at the calendar in the screenprint below you will note that the missing date does not really get the attention it deserves. It looks just as gray as all the dates for the first week of January which are also shown in December.
My enhancement request is: Give the missing dates for a Control-M calendar a different color to distinguish them clearly. Or, alternatively, do only show days belonging to a specific month for that month and do not show the days from other months. This reduces the chance that you make errors during calendar preparation.
