Can a signature be required for Opt-Out in CRM?
Yes, a signature can be required for Opt-Outs.
On the related Consent Header, set the Signature_Required_On_Opt_Out_vod checkbox to TRUE.
If it is set to FALSE, then the Signature/ Paper Consent ID is not required when only Opt-outs are being captured.
Note: Signature_Required_On_Opt_Out_vod = TRUE, but if the Consent_Type_vod.zvod_Signature_Capture_vod field is not placed on the page layout, the Signature/ Paper Consent ID capture is not possible. Therefore, opt-outs are saved without Signature/ Paper Consent ID.
