I am in my test environment and I upload via DMT my MPS, I see it in my query and MPS Entry, I can even see the MPS Demand in TimePhase.  Then I run MRP and my MPS Demand in TimePhase is gone, but I still see the entries in my query and MPS Entry.  The logs of MRP don’t indicate any MPS Demand.

Anyone run MPS on 9.05.702A Prog here?

Out of curiosity, have you tried to MANUALLY enter any MPS and run the process? it is possible you are missing some key data in your DMT load.

I did enter some manually, but that disappeared as well.  And when I say disappeared, I mean the MPS Demand from TimePhase is gone.  But I still see it in the MPS tables.

Do you have unfirm jobs? They should override the MPS demand, since the MPS resulted in the jobs; you wouldn't want a second set of jobs after firming the first set. Forecasting gets consumed for the same reason.

can you post a screen shot the Time phase with the MPS in it before you run MRP and then another after you run it with the MPS now "gone". are there any customizations or BPMs in the environment that might be doing some funny business?
