Example 1

You want to determine if your supplier has delivered the requested quantity on time. You have set up the following time windows:

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.

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 for the first assignment phase. In Figure 1 equal assignments are possible for the request SLs and ASN items dated 15.11.2010 and 21.11.2011. To assign the quantities of the other request SLs to quantities of the ASN items, SAP SNC splits quantities in the request SL dated 10.11.2010 and the ASN item dated 27.11.2010. After the split, SAP SNC is able to make two more assignments between request SLs and ASN items. Figure 1 shows the assignments that SAP SNC makes to determine which quantities are on time. The black lines represent the assignments. The green circles show the remaining quantities.

In example 1, after the first assignment phase quantities still remain that SAP SNC cannot assign. Despite the remaining quantities being equal to each other, SAP SNC cannot assign them to each other as they lie outside of the time window defined for the second assignment phase. Therefore, SAP SNC classifies these quantities as overdeliverred (for the remaining quantity from the ASN item dated 10.11.2010) and overdue (for the remaining quantity from the request SL dated 27.11.2010). Table 2 shows the results of the supplier performance measurement.

Example 2

You want to determine if your supplier has delivered the requested quantity on time. You have set up the following time windows:

Table 3 shows the quantities of 3 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.

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 for the first assignment phase. In example 2, equal assignments are not possible for any of the request SLs and ASN items. Therefore, to assign the quantities of the request SLs to quantities of the ASN items SAP SNC splits quantities in the request SLs dated 10.11.2010 and 20.11.2010 and in the ASN item dated 12.11.2010. After the split, SAP SNC is able to make assignments for those quantities that are within the time window defined. Figure Phase 1 shows the assignments that SAP SNC makes that determine which quantities are on time. The black lines represent the assignments. The quantities that remain are not within the time window defined to determine on-time quantities.

After the first assignment phase, SAP SNC runs the second assignment phase to classify the remaining quantities as early or late, or overdeliverred or overdue. SAP SNC makes assignments for the remaining quantities (valid assignment are shown with the green lines in figure Phase 2) that are within the time window defined for the second assignment phase. These assignments determine if the quantities are early or late. SAP SNC also classifies the remaining quantities that cannot be assigned in the second assignment phase, as they are outside of the time window, as overdue or overdeliverred (shown with orange circles in figure Phase 2).

Table 4 shows the results of the supplier performance measurement.
