Using ATP Processing Features
Since the system calculates ATP only on confirmed order lines, the way the system enforces ATP depends on how the order is entered:
• Entered as confirmed in an order maintenance program, such as Sales Order Maintenance (7.1.1), or confirmed by changing Confirm to Yes for the line
• Confirmed using a batch confirmation program, such as Sales Order Confirmation (7.1.5)
• Created from a customer’s purchase order imported using EDI eCommerce
Determining ATP during Order Entry
The system determines ATP during order-processing functions when you enter confirmed order lines in one of the following programs:
• Sales Order Maintenance (7.1.1)
• Material Order Maintenance (10.7.1 or 11.11.1)
• RMA Maintenance (11.7.1.1)
During order-line entry, an ATP pop-up window displays under the following conditions:
• ATP Enforcement is Yes in Sales Order Control.
• The ATP enforcement level is set to Warning or Error for the item. See ATP Settings for Items.
• The quantity ordered is unavailable for the specified due date for a confirmed non-EMT inventory order.
The pop-up window lets you select alternate due dates and review ATP quantities when the full order quantity cannot be filled by the specified due date.
