Workflows represent the company’s different document flows. They are completely configurable and define the path that any individual OpenERP object (such as an order) must follow, depending on the conditions (for example, an order above a certain value must be approved by a sales director, otherwise by any sales person, before the delivery can be triggered).
The figure Workflow for order SO005 shows the standard workflow for an order. You can show it from the Debug Mode by clicking Print Workflow. Select an order, then Print Workflow to show the workflow below.
The chapter Process provides all of the information needed to create and modify technical workflows and cross-company processes.
