Cumulative Quantities in Scheduling Agreement
Processing 
Within Service Parts Management (SPM) using scheduling agreements, the vendor and the purchasing department can agree on the requested and delivered quantities and, when a fiscal year change take place, can use the agreed cumulative quantity to correct the goods receipt cumulative quantity (GR-CQ).

The agreed cumulative quantity is subtracted from the goods receipt cumulative quantity so that, when the year change takes place, the purchasing department and the vendor are working on the basis of the same GR quantity. The agreed cumulative quantity is calculated on the basis of the reconciliation date.
The processing of the scheduling agreement item (for example, creating a release and sending it to the vendor) must take place after the reconciliation date. In this case, the agreed cumulative quantity is subtracted from the goods receipt cumulative quantity. The goods receipt cumulative quantity and the release quantities displayed as the cumulative quantity are reduced by the amount of the agreed cumulative quantity.
Reconciliation using cumulative quantities comprises the following functions and enhancements:
· You can reconcile the cumulative quantities on the basis of the quantity promised by the vendor or on the basis of the goods receipt quantities that have actually been received from the vendor.
See Reconciliation via Cumulative Quantities and Set the Agreed Cumulative Quantity for the Reconciliation Date or Execution Date)
· You can carry out mass maintenance of reconciliation data.
See Mass Maintenance of Reconciliation Data
· You can transfer this additional data in the IDoc DELVRY03 Delivery Interface to SAP APO for example.
You cannot use OLTP scheduling agreement items for Service Parts Management (SPM) because, schedule lines in the planning horizon that have been transferred to the vendor via release, for example, can no longer be deleted in SAP APO.
You cannot change schedule lines for OLTP scheduling agreement items in SAP APO in functions such as Planning Service for Distribution Requirements Planning, External Procurement – Schedule Maintenance (transaction /SAPAPO/SPPDRPSB), Product Planning Table (transaction /SAPAPO/RRP3) or SNP Planning Table.
You can transmit this additional data to SAP APO in the scheduling agreement item via IDoc DELFOR02 – Delivery Schedule/JIT Schedule.
