|Description||The user has set-up Salesforce to Salesforce, published the Object, and customized the Object's Page Layout to display the External Sharing Related List but the "Forward this <Object>" (e.g. Forward this Lead) button is missing, hence, the record cannot be shared to a connection.|
|Resolution||Here are the following reasons why the "Forward this <Object>" button is missing from the External Sharing Related List:
1. The user has only the "Read" permission on the record. The minimum permissions required to assign records to a connection would be a combination of both "Read" and "Edit" on the record.
2. The partner company did not subscribe to your published Object. The user should coordinate with their partner company's system administrator and have them subscribe to the published Object.
