Remove default attendees from Appointment (in reference to opportunity)

[DAcker]

Hello all,

is it possible to change the customizing so that if I create a new appointment in reference to / out of the opportunity the attendee is empty?

Currently the SAP standard adds as attendee the contact person from the opportunity. See screenshot for an example:

I searched in the Business Configuration for Activities and in the scoping element under "Maintain Involved Parties for Appointments".

But in there I didn't find any determinations, so I can't untick any active determination in order to remove the default attendees.

Thanks for help.

Best Regards, Deborah
