| To compute distribution order quantities |  |
| When Enterprise Planning carries out distribution planning, the volume that is planned for a supplying relationship 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 distribution 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 = min(REQ, RQ x	 PE / 100.0)
Where:
OQ | ordered quantity
REQ | remaining quantity
RQ | originally required quantity
PE | percentage
The percentage is defined in the Percentage field in the Supplying Relationships (cprpd7130m000) session. If a supplying relationship consists of two or more lines of which the validity period (partially) overlaps, ERP LN must rescale the percentages of the corresponding lines if that total is not equal to 100%. Example A supplying relationship consisting of three lines exists for Item X in warehouse D:
Receiving item | Supplying item | In warehouse | Percentage | Period
Item X |  | D | - | -
| Item X | B | 80% | 1/1/2003 to 7/1/2003
| Item X | C | 70% | 7/1/2003 to 12/31/2003
| Item X | A | 30% | 1/1/2003 to 12/31/2003
A demand of 100 pieces placed on item X in warehouse D in the period from 1/1/2003 to 7/1/2003 results in: Delivery of 73 pieces from warehouse B to warehouse D: (0.8 * 100)/(0.8 + 0.3) Delivery of 27 pieces from warehouse A to warehouse D: (0.3 * 100)/(0.8 + 0.3) The same demand in the period from 7/1/2003 to 12/31/2003, results in: Delivery of 70 pieces from warehouse C, that is, 70% of 100 pieces. Delivery of 30 pieces from warehouse A, that is, 30% of 100 pieces. For the demand of 100 pieces placed on item X in warehouse D in the period from 7/1/2003 to 12/31/2003, ERP LN does not have to rescale the percentages of the lines of the suppling relationship, because they total exactly 100%. Percentage/Capable If the Allocation Rule field is Percentage/Capable, the calculation proceeds as follows: The same formula as above with the following addition:
     OQ = min(OQ, MQ)
Where:
MQ | maximum quantity that can be ordered
Capability If the Allocation Rule field is Capability, the calculation proceeds as follows:
     OQ = min(MQ, REQ)
Note ERP LN determines the maximum quantity that you can order from a supplying cluster by using capable-to-promise techniques. Related topics To select internal suppliers Lot sizing Capable-to-promise, an overview |
