In the CRM sample app ...
#1 In the Appointment table, there is varchar column called RecRule column that holds a simple recurrence rule that appears to be fairly basic.
#2 BUT there also is a table called APPTRECURR which has columns that align with managing recurring appointments. The db table is not in use as far as I can tell, but it seems it would provide for a more sophisticated approach.
Is ApptRecurr a legacy table or is it part of the path forward?
I'm asking because I believe I'm going to need more sophistication vs less. For example, I do not believe there is not an out of the box way to create/edit recurring appointments using custom forms.
