I have copied a workflow that export other kind of dataset. I changed the -include_related_type from the other dataset to DirectModel, it doesnt show any error but it doesnt export the JT file either. Should I change some other thing?
My guess is your workflow is using a handler PIE-export-to-plmxmlfile. This handler will be using a transfermode which is designed to export a certain type of dataset(s). The transfermode will be identified in the 'context' argument. Edit the closure rule used by the transfermode or create a new one in plmxml administration by adding your dataset type.
