Symptoms

EnterpriseOne 9.2
MRP Processing (R3483) is not recognizing purchase order lines with a negative quantity (which means to return inventory from stock to the supplier. Subsequently, this purchase order "demand" is not seen and inventory goes negative. The Time Series (P3413) shows negative, and the Supply and Demand Inquiry (P4021) shows negative ending availability, the Detail Message Review (P3411) does not ask to create messages to cover this "demand." It is not traditional demand as a purchase order quantity is typically defined as supply as we are receiving inventory into stock. A negative purchase order quantity means that we are taking inventory out of stock due to a return.

Note 1 - R3482 works without a problem as the UBE recognizes the negative purchase order quantity and suggests messages if there is not enough inventory and/or planned orders to cover demand.
Note 2 - Past Due negative quantities is not the culprit as R3483 does not recognize future quantities as well.

The workaround is to create a positive quantity detail line for the same purchase order with the same quantity as the negative line AND freeze the purchase order.
