I'd like to lend weight to this requirement. Many users of our application use Sage 50 where Departments and Cost Centers are heavily entrenched and will be expected as a critical element to transaction postings . Currently I understand the above to mean that as things stand these attributes can't be sent with sales invoices for example (this does answer some of my confusion over where these elements are on the invoice API endpoint)? Could you clarify the current expectation for businesses integrating with Sage Business Cloud, where Dept & CC are managed / maintained and used on both sides of the fence? By the sounds of this we can only assign a nominal code at this point in time?
