I want to know how does OpenERP uses BPM or workflows. From what I read it seems is used more as a reporting tool than a design tool. Am I wrong? Anyone can point me out to some tutorial on how to design a process using the BPM tool. From what I have read I've seen that the BPM in OpenERP is not compatible with other tools like BonitaSoft or ProcessMaker.
You can graphically interact with processes/workflows and edit them via the graphic display driving you to the attributes behind them. That's the way you should think of customizing workflows.
The tool is not compatible with BonitaSoft or ProcessMaker.
