Accuracy of the ASN

You, the customer, can use this rating criterion to rate the performance of the supplier on their ability to accurately record data in the advanced shipping notification (ASN). To determine the supplier’s accuracy, SAP Supply Network Collaboration (SAP SNC) compares the data in an ASN item to the purchase order (PO) item or scheduling agreement release (SA release) item that the ASN references. SAP SNC can determine the accuracy of the ASN item on the basis of three checks. You can activate one or more of the checks. The checks verify the following:

Is the product valid?
To determine the validity of the product, SAP SNC compares the product entered by the supplier with the product requested by the customer in the PO or SA release item.
Does the ship-to location of the supplier match the ship-to location of the customer?
To determine if the ship-to locations of the supplier and customer match, SAP SNC compares the ship-to location to which the supplier plans to delivers the goods to the ship-to location where the customer actually wanted the goods delivered.
Is the quantity correct?
To determine if the quantity is correct, SAP SNC compares the quantity entered by the supplier in the ASN item with the quantity requested by the customer in the PO or SA release item.

To use this rating criterion, you must activate the business function Supply Network Collaboration 2 (SCM_SNC_GEN_2).

Prerequisites

You have made the following settings in Customizing for Supply Network Collaboration under Start of the navigation path Tools Next navigation step Supplier Performance Management End of the navigation path or on the SAP Easy Access screen under Supply Network Collaboration Tools Supplier Performance Management :

You have activated the checks for the ASN accuracy rating criterion. You activate the checks in the Make Global SettingsCustomizing activity.

To determine the accuracy of the ASN based on quantity, you have made the following settings:

You have set up a quantity tolerance in the Define Quantity Tolerance Customizing activity. The tolerance is valid for the quantities of the PO or SA release item.
You have set up a time window in the Define Time Window Customizing activity. You set the time window for the request schedule lines (request SL) of the PO or SA release item.
You have made settings in the Make Global Settings Customizing activity to determine to which request SL SAP SNC assigns quantities from the ASN item in the second assignment phase.

Scoring the Supplier in Supply Base Performance Analysis

To score the supplier, SAP NetWeaver Business Warehouse (SAP NetWeaver BW) uses the formula number of accurate ASN items / total number of ASN items.

Determining the ASN accuracy Based on the Quantity

SAP SNC considers an ASN item accurate if its quantities match the quantities of the request SLs of the referenced PO item or SA release item and if they are within the defined time window. To determine the accuracy of an ASN item, SAP SNC runs two assignment phases that assign quantities from the ASN items to quantities from the request SLs. For more information, see Example.

Example

The customer wants to determine the accuracy of the supplier’s ASNs based on quantity. The customer has set up a the following quantity tolerance and time window for the request SLs:

Quantity tolerance: -0% and + 50%
Time window: +/- 3 days

In the Make Global Settings Customizing activity, the customer has also set the Assign ASN Quantity field to Next ASN Item. Table 1 shows the quantities of four request SLs from the customer’s PO or SA release item as well as the quantities from several ASN items that the supplier has created to fulfill the customer’s request.

Date	Request Schedule Line Quantity	Date	ASN Quantity	Result
10.11.2010	50	10.11.2010	50	accurate
15.11.2010	100	12.11.2010	50	accurate
20.11.2010	120	17.11.2010	100	accurate
25.11.2010	100	22.11.2010	50	inaccurate
		27.11.2010	50	inaccurate
		30.11.2010	50	inaccurate

The figure Phase 1 shows the assignments that SAP SNC makes to determine the accuracy of the ASN. The black lines represent the assignment.

This graphic is explained in the accompanying text.

Phase 1

SAP SNC starts its first assignment phase by matching those request SL quantities that can be matched equally with the ASN items that are within the time window. In the figure Phase 1 an equal assignment is initially only possible with the request SL and ASN item dated 10.11.2010. To assign the quantities of the other request SLs to quantities of the ASN items, SAP SNC must split quantities in both the request SLs and the ASN items. In this example, SAP SNC has been able to find matches for most quantities. Nevertheless, after the first assignment phase has finished some quantities in the request SLs remain unfulfilled by ASN items (remaining quantities). Furthermore, one ASN item lies outside of the time window set up for the request SLs.

After the first assignment phase, SAP SNC uses its second assignment phase to try and match the remaining quantities from the request SLs. SAP SNC assigns the remaining request SL quantity to the next ASN item (shown using green arrows in figure Phase 2).

Note Note

Whether SAP SNC assign the remaining request SL quantity to the closest or the next ASN item is determined by your Customizing settings.

End of the note.

In this example, because the quantity of the next ASN item is not enough to fulfill the remaining request SL quantity, SAP SNC considers the ASN item as inaccurate. Lastly, SAP SNC categorizes the quantities of the ASN item that lie outside of the time window (circled in orange in figure Phase 2) as inaccurate.
