In many cases new ERP implementations with Dynamics 365 software contain both Finance and Operations and Customer Engagement. This means that outgoing documents need to be filled with data, and processed from both environments where in the past most of the documents were processed from the F&O environment. So the data needs to be structured and combined into proper XML data structures for designing, distributing, validating and archiving documents. Microsoft Azure and Blobstorage services are the best mechanisms from a performance and security point of view for consolidation of data from D365 F&O and CE into proper outgoing documents.
