Microsoft just published another Visual How To, Creating a Custom Approval Workflow for SharePoint Server 2007 Using SharePoint Designer 2007, written by yours truly. This Visual How To explains how to build a SharePoint Designer approval workflow for the sample expense report form template that comes with InfoPath 2007. The article and video show how to modify and then publish the form template to a SharePoint document library, define a new workflow and attach it to that document library, and add conditional logic within the workflow designer. This codeless approach to building an expense report workflow is an alternative to working in Visual Studio 2008, which fellow 3Sharp developer Mike Rand describes in the Visual How To titled Building an Expense Report Approval Workflow for SharePoint Server 2007 Using Visual Studio 2008.
