To compute purchase order quantities

When Enterprise Planning carries out purchase-order planning, the volume that is planned for a supplier depends on the value of the Allocation Rule field in the Supply Strategy (cprpd7120m000) session.

The resulting volume is checked against the lot sizing rules. The ordered quantity can be divided over multiple purchase orders as a result of the lot sizing. See Lot sizing.

Percentage

If the Allocation Rule field is Percentage, the calculation proceeds as follows:

 OQ = RQ x PE / 100

Where:

OQordered quantity
REQquantity that remains to be planned
RQoriginally required quantity
PEpercentage

 

If the ordered quantity (OQ) is greater than the quantity that remains to be planned (REQ), OQ is set to REQ.

The percentage is defined in the Sourcing Percentage field in the Item - Purchase Business Partner (tdipu0110m000) session.

Percentage/Capable

If the Allocation Rule field is Percentage/Capable and the just calculated value of the ordered quantity is greater than the maximum quantity that the supplier can deliver, the ordered quantity is reduced accordingly.

See the Supplier Capacity field in the Item - Purchase Business Partner (tdipu0110m000) session.
