This idea follows a ticket we submitted but was rejected as not on MS roadmap. We suggest to fix the subworkflow behavior. when incorporated in a workflow (as a last step) the PO should not be approved before the subworkflow starts but after it is finished. https://community.dynamics.com/ax/f/33/t/282013 Today (release 8.1), we have 25 companies and each has a PO workflow with a local part and a common part. We want to have a subworkflow for the common part, as it reduces the cost of maintenance. In case of modification we would only have to update the subworkflow once instead of 25 workflows.
