RE: On Recurring Appointment Master, not able to add/map Linked attribute(Propagation Data) for optionset field type
Hi partner,
Actually if you want to set option set field mapping between Appointment and Recurring Appointment, you should create an option set field in Recurring Appointment first.
For example I want to map a field named "Mapping Option", I need to create it first in Recurring Appointment, and then select "create new" in "Data Propagation" section.


This action will create a same option set field in Appointment with the same name.
Save and Publish, then go to Appointment form editor.
We will find that the "Mapping Option" field is already in the field list in Appointment. Put it on the form and let's have a try.

We created a new appointment, set the value of "Mapping Option" and create a new Recurring Appointment.
Appointment Form

Recurring Appointment Form

Hope it helps.
Best Regards,
Leo
