RE: How to post batches in Great Plains using GP WebServices
                     
                    
                      
                        Please look at Winthrop Development Consultants, Batch Posting Service Toolkit (BPST).
It does exactly what you need at a very reasonable price. It was designed to allow for real-time posting immediately after the transactions we imported.
It exposes the standard series posting routines for all core Dynamics and Project Accounting batches as a web service endpoint using the REST based service procedures provided by SBA (Service Based Architecture).
A single URL call can post a batch for you.
There are also web services for creating, editing, and deleting batches as well as retrieving a list of batches ready to be posted.
If you want other methods of calling BPST it can be called from Dexterity or VSTools (C# or VB.Net) or even from GP Power Tools (GPPT) using triggered, scheduled or manual processes.
