Hi everyone since Commerce 1808 BPMN-related extensions were deprecated and removed (ref. https://help.hybris.com/1808/hcd/8bc0c14886691014a0d4f274a720596f.html)
there is currently no graphic modeling tool available modeling of complex workflow is not as well supported as you may expect it.
By default, the Hybris workflow extension does not support a combined usage with other workflow engines. This is because it is based completely on the Hybris type system and does not provide standardized interfaces like BPEL. For details contact Hybris Professional Services.
Is something planned as an alternative to get customers able to graphically model their workflow? With BPMN we were able to model with any 3rd party BPMN editor.
