Hi,
When a customer submits a ticket via the Customer Portal Form, then for us it is necessary to get his/her phone number and address.
Fundamentally the phone and address data are part of the Contact record.
Therefore I do not want to create additional custom fields for them, because they would be duplicated this way.
What is the best way to collect such data via the Customer Portal Form, even if the data will not be populated with the built-in contact fields used for the same purpose.
Thank you for your suggestions!
