Scenarios There are two main business scenarios for Ad Hoc Correspondence and Correspondence Reviewer – the on-demand scenario and the batch scenario. In both scenarios, the web applications are integrated into the business workflow of the customer. The final documents are formatted and distributed by a StreamServer application according to the configuration made in Design Center. On-demand scenario In Ad Hoc Correspondence, a new personalized document is created for a specific customer. Correspondence Reviewer can be used to review the document before it is formatted and distributed to the customer. Batch scenario A document is created from a batch of input data sent to a StreamServer application. In Correspondence Reviewer, the document is reviewed before it is formatted and distributed to the customer. Ad Hoc Correspondence can be used to edit the document before it is approved.
