CUM (cumulative) management lets you track the cumulative quantity received over a given time period for each supplier site/item in a ship-to organization. This time period is called the CUM period, and generally relates to a meaningful business time frame like a quarter or model year in the automotive industry.

CUM management is enabled at the organizational level. You can determine, which transactions affect the CUM calculation as well as manually adjust the CUM quantities.

CUM management is enabled in the Supplier Scheduling Options window, where you can also select whether Return to Supplier (RTV) transactions and their associated corrections are included in the CUM calculation.

At the start of a CUM period, all quantities are initialized to 0. As goods are received against a Supply Agreement Release for scheduled items, the CUM is updated. Receipts against other document types do not affect the CUM.

Supplier Scheduling automatically maintains the CUM quantity for the following transactions:

• Increase for receipts and match transactions

• Reduce for returns to supplier (RTV)

• Reduce or increase for receipt quantity correction

• Reduce or increase for RTV quantity correction

CUM Periods are defined in the CUM Periods window. See Defining CUM Periods.

Reviewing and Adjusting CUM Quantities

You can review all transactions affecting the CUM for a selected CUM period, supplier site, ship-to organization, and item, and manually change the calculated quantities if necessary.

If an item is received in one CUM period and then returned to the supplier in another CUM period, the return transaction updates the CUM quantity in the period the original receipt took place.

You can view and adjust CUM period quantities in the CUM Period Items window.

An item's transaction history can be reviewed in the CUM History Report. See: CUM History Report.
