When a prospect/Profile unsubscribes from a journey, Which system dataset in AJO captures the information. How Journey uses this dataset to exclude the member from further communications when journey uses different identifier
It depends on what type of consent is configured (channel, identity or subscription list) https://experienceleague.adobe.com/en/docs/journey-optimizer/using/email/email-opt-out#opt-out-external-lp
Consent data is stored in the XDM under consents.marketing object
For consent at channel level,If consents.marketing.email.val is set to n (via channel level unsubscription), the profile will stop receiving marketing emails. This is to prevent profile from receiving marketing communications through a particular channel.
AJO manages identity-level consent through the consents.idSpecific map where in it is managed per email address.
Ex:- consents.idSpecific.{Namespace}.{Identity}.marketing.{Channel}.val
