Creating ASNs for a Purchase Order Item 
If you, as supplier, want to inform your customer about an upcoming delivery of a purchase order item, you manually create an advanced shipping notification (ASN), which refers to the purchase order item, on the Web UI of SAP Supply Network Collaboration (SAP SNC) and publish the ASN. SAP SNC sends the ASN with a DespatchedDeliveryNotification to the back-end system of the customer. You can also generate the ASN in your back-end system and send it to SAP SNC. SAP SNC forwards the ASN to the customer’s back-end system.
The item must fulfill the following conditions so that you can create an ASN for the item in the standard system:
●
Confirmation
control in SAP SNC permits confirmations for the item.
● The PO item has the status Open, Partially Delivered, or Delivery Completed.
You cannot create ASNs for a PO item with the status Rejected, Canceled, Closed or Blocked.
●
The
ASN-based due
quantity is greater than zero.
● The PO item is not a statistical item.
Statistical items are only relevant in Service Parts Management if the customer back-end system (SAP ERP with activated Service Parts Management) has performed supersession for the item. The supplier is therefore not to deliver the product that the customer originally planned to order, but another one.The customer back-end system marks the main item with the originally ordered product as a statistical item in the purchase order, and creates a subitem with the replacement product for the main item. Only the subitem is delivery-relevant. You can therefore also create an ASN in SAP SNC for a subitem.
If you publish an ASN for a purchase order item in SAP SNC, SAP SNC creates an ASN-confirmed schedule line for the purchase order item. You cannot change this schedule line manually in SAP SNC.
Based
on the ASN-confirmed schedule lines, SAP SNC automatically determines which
request schedule lines of a purchase order are due. For these schedule lines,
the supplier must still publish ASNs. For more information, see
Determining Due
Schedule Lines.
In the Web UI, you can use the Related ASNs function to display the ASNs that the supplier has created for the purchase order.
To create ASNs in the purchase order details, the following options are available:
● At schedule line level
If you want to create an ASN with an ASN quantity the same as the due schedule line quantity, select the request schedule line and choose Create ASN for Schedule Lines. If you select several schedule lines, SAP SNC proposes the sum of the due quantities as the ASN quantity.
● At item level
If you want to create an ASN with an ASN quantity the same as the complete due item quantity, select the request schedule line and choose Create ASN for Items. If the ship-from location, ship-to location, and means of transport are all the same, you can also create an ASN for several selected purchase order items. SAP SNC creates an ASN item for each purchase order item.
