How do I remove the membership No. from Annual Statements, Membership Renewal Notices, Membership Confirmation Notices?
If you are looking to remove or update the label "Membership No.", then you can update the "Membership ID Label" field value on the related Payment Form.
If you are looking to remove the label and remove the Membership No. value, then you will need to use a Letterhead graphic to replace the entire top header part of the document.
