Contact Person linked to multiple Corporate Accounts from SAP CRM to SAP Marketing Cloud

Dear SAP Support,

in SAP CRM we associated a Contact Person for the first time to a Corporate Account (relationship category: BUR001). The relationship was correctly replicated to SAP Marketing Cloud.

Subsequently, we associated the same Contact Person to another Corporate Account (relationship category: BUR001). This new relationship was correctly replicated to SAP Marketing Cloud but the previous relationship between the Contact and the first Corporate Account was deleted.

Could you kindly verifiy why SAP Marketing Cloud has this behaviour? We expected that both the relationships were maintained also in SAP Marketing system (as it happens in SAP CRM system).

Thank you very much,

Alberto
