Symptom
"Multiple Address" function has been activated for both customer master data and the sales document. However, the "Address Proposal" button is greyed out when trying to change the partner address under the "Parties Involved" tab for the subscription item of solution order. the "Address Proposal" button is available for the sales item of the solution order.
Environment
SAP S/4HANA Cloud Public Edition
Resolution
The issue is due to the current system design that the "Multiple Address" function is not supported in the Subscription Billing system. Therefore, it is not possible to change the partner address for a subscription item in the solution order and the "Address Proposal" button is greyed out. To have this functionality available in the future, raise a feature request through the Customer Influence Portal.
