Issue appears to stem from orphaned demand that is being left in the Logical Unit "Pegged Supply Demand" in the view "&AO.PEGGED_SUPPLY_DEMAND_EXT". Once we manually cleared those orphaned records, the demand disappeared.
It looks like that table is getting skipped by any cleanup jobs after you turn off the "MS Level 1" forecast for that part.
My question is why is this not getting cleared, or is this a MRP issue that is not clearing the pegged demand?
Is there any steps to clear this demand qty?
