I'm now playing with the trial of Nintex Workflow and Forms, 2016, for our deployment of SharePoint 2016 that we will be upgrading to in Q4 of this year. So far, I like the ease of use and power of Nintex's solutions. That all being said: has anyone out there successfully integrated any Workflow procedures with Dynamics GP--be it through BCS, SQL query, web service, etc.? In particular, I want to pass information to/from GP's Purchase Order and Invoicing tables, to essentially create a PO request and Invoice approval workflow between employee and manager, then manager to accounting, back around to employee for Invoice approval, etc. I am interested in hearing any success or failure stories any of you may have out there as to whether or not your attempts sank or swam, and why did they sink if it didn't work out for you? I look forward to any replies and thank you all in advance!
