In the SAS^® Management Console Schedule Manager plug-in, you might see the following error when adding a new time event to a flow

(Error: Unable to validate the time event.)

This error occurs when you select a calendar name that starts with DL_. For example, if you select DL_CAL and click OK in the new Time Event dialog box, you see the error. 

To work around the issue, use the Process Manager calendar editor to save the problem calendar with a new name that does not start with DL_.
