Thanks. If I understand correctly, the design pattern for the business rule would be:

•  Trigger: a record on the consumer side satisfies the criteria for the Service Bridge integration i.e. the related remote task on the consumer side is created. In our use case, we are bonding the incident records that have a specific assignment group.
  • The code would be run on afterUpdate to make sure that a consumer remote task is created.
• Logic: copy all attachments, work note and comments from the consumer eBonded incident records to the related remote task

The Service Bridge would then automatically do its magic and copy them to the corresponding remote task on the provider side. 

Comments and attachments would then automatically be copied to the target record on the provider side. For the work notes, additional code is needed and you have already posted an article on how to do that.

Does this sound right?

Of course, any code examples would be welcome, as always 😁
