Demand Entry - Create New Sales Order

I have a PO in the Demand Entry Screen as a Firm document, but it is not creating the sales order.

I have two error messages in the the Log:

  1. ZeroQtyDemandSch - New Demand found with quantity less or equal than zero. Skipping Demand Schedule. and Triggered by ******
  2. Order Detail not found

Neither the header nor the line items have a rejected or error message.

Nothing shows up in the Demand Workbench.

Where should I look next to push this PO from Demand Entry to an order?

Thank you,
Tim
