ATP Behaviour with Planned Receipts

An Overview on ATP in Sales and Distribution ProcessATP Available to Promise:When a sale order is processed, the available quantity and the delivery date for the goods have to be confirmed to the customer.

To arrive at the available quantity and delivery date, all necessary processing activities which take place before delivery have to be considered.

Data relevant to shipping, procurement have been set at various master data levels so that ATP uses these to arrive at the delivery date and available quantity.

However in this presentation we would be getting only into the details on Procurement side.

The ATP quantity (ATP = Available To Promise) is calculated from the warehouse stock, the planned inward movements of stock (production orders, purchase orders, planned orders) and the planned outward movements of stock (sales orders, deliveries, reservations). This type of check is performed dynamically while creating the sale order.

In Nut shell:

Available-to-promise quantity. This is the quantity still available to MRP for new sales orders.

The ATP quantity is calculated according to the following formula: ATP quantity = Warehouse stock + Planned Receipts - Planned Issues.Our focus in the next slides would be on the Planned Receipts.Let us see the screenshots from SAP explaining the ATP on the basis of incoming stocks.Screenshot 1: Stock Overview Material -38203810 at Plant 5311 (TCODE MMBE) Screenshot 2: Stock Overview Detailed View Screenshot 3: Stock Requirements list for Material -38203810 at Plant 5311 (TCode MD04) Screenshot 4: Stock Requirements list for Available Quantities screen Total Receipts = 26592 PC; Confirmed Issues = 46 PC; Therefore, ATP quantity = 26592 46 = 26546 PC.Screenshot 5: Creation of Sale order (TCode VA01) (Order Qty 30000 PC) Screenshot 6: Sale order creation ATP screen Order confirmed for 26546 PC.

At this stage we do not have any incoming purchase orders.

Screenshot 7: Stock Requirements list for Material -38203810 at Plant 5311 No purchase order available in MD04, however we have a Purchase request, but this is not considered as the scope of check in Screenshot 6 shows that Purchase request should be excluded in ATP.

Screenshot 8: Creation of a Purchase order: PO created for 100 cases. (i.e) 2400 pieces Confirmed date on PO is 30.05.2011.Screenshot 9: Purchase order saved: Screenshot 10: Stock Requirements screen updated with purchase order Stock availability for the material for Purchase order created is 31.05.2011. This is because of the GR processing time available in the material master data. This is available in the Delivery tab of Purchase order as shown in the next screenshot.Screenshot 11: Delivery tab of Purchase order shows 1 day processing time. Screenshot 12: Creation of Sale order (TCode VA01) (Order Qty 30000 PC) Screenshot 13: Creation of Sale order ATP screen Order is confirmed for 26546 PC on 27.05.2011 based on the stock in plant, and 2400 pieces are confirmed on 31.05.2011 based on the PO created in screenshot 9.

Screenshot 14: Order creation ATP screen Scope of check Screenshot 15: Change an existing Purchase request Purchase Req date is changed to 28.05.2011.Screenshot 16: Purchase Request display Quantities / Dates Tab: Delivery date requested is 28.05.2011. To meet the delivery date, system needs 1 day for GR processing, (i.e.) 27.05.2011. Request date 26.05.2011 is the date the Purchase request was created.Screenshot 17: Stock Requirements list to show the Purchase Request details: Date on the MD04 screen appears as 30.05.2011. This is because there is a 1 day processing time for plant 5311 (defined in config) and the calendar is a 6 working day. Delivery date + 1 day = 28.05.2011 + 1 day (29.05.2011 holiday as Sunday), material is confirmed on 30.05.2011
