Yes. I am running a test now in our DEV environment. I created a new MPS demand and I am running MRP Net Change.to see if i can see the demand and if it creates a job.
So i just got off the phone with Epicor and this is a known issue. They said the first MPS will be consumed but a job before it. So a dummy MPS must be created then the real MPS deamand will create jobs. It is fixed in Epicor 10 under company config and MRP to check a check box to allow MRP to create MPS jobs.
