Function documentationRestriction Check During Automatic Replenishment Planning

 

Main Restriction Check

Requirement quantity optimization checks whether an order proposal fulfills the main restriction.

If the order proposal does not fulfill the minimum restriction, requirement quantity optimization checks whether the order quantity is so small that SAP F&R should cancel the entire order proposal (due to the percentage threshold to discard the order proposal). If this is the case, the system issues an exception. Otherwise, requirement quantity optimization checks whether the order proposal (OP) can be optimized according to the restriction parameters. To do so, it also uses the restriction parameters in the Profile for Requirement Quantity Optimization.

If the quantity for optimization is not large enough, it remains as it is and the system issues an exception. Otherwise SAP F&R optimizes the order proposal on a requirement-dependent basis. In this case, the system uses the preplanned requirement from future demand periods to reach the minimum quantity. This is done for all of the supplier's products that can be ordered on the order proposal date. If the system has taken several periods into account to achieve this, it issues an exception.

SAP F&R concludes optimization in the demand period based on the Fill-up method parameter: when the minimum order quantity is reached or the system has taken the requirement into account for all products within a particular period. If the minimum order quantity for a supplier is not reached even through the system has added all the demand periods for all of the supplier's products, the system issues an exception.

Additional Restriction Check

After optimizing the order proposal according to the main restriction, you can perform an additional restriction check.

  • Additional minimum restriction

    You can check another minimum restriction from a different restriction type (price, quantity, weight,or volume). In the restriction profile you can define a percentage for discarding the order proposal. If the optimized quantity is not above this percentage rate, in relation to the minimum restriction, the system discards the order proposal.

  • Restriction check for multiples

    SAP F&R checks whether the optimized order proposal quantity is a multiple of a defined value. If not, the system increases the quantity so that a multiple is reached. If the smallest multiple is not reached (although SAP F&R has added all the requirements from all demand periods together) the system checks whether the quantity is greater than the percentage rate at which the entire order proposal is discarded. If not, the system does not create an order proposal and generates an exception; if so, the system creates an order proposal and also generates an exception.

  • Discount scales

    You use discount scales when the supplier gives discounts for defined order quantities. Optimization checks whether the optimized order quantity qualifies for at least the lowest discount segment. If not, SAP F&R increases the quantity with the requirements for future demand periods until the lowest discount threshold is reached. After this, the system calculates the most economical order quantity, including all the defined discount scales that apply from the existing demand periods. The system compares the supplier's discount with the percentage of storage costs. If the smallest discount scale is not reached (although the system has added all the requirements from all demand periods together) requirement quantity optimization checks whether the quantity is greater than the percentage rate at which the order proposal is discarded completely. If not, the system does not create an order proposal and generates an exception; if so, the system creates an order proposal and also generates an exception.

  • Fallback strategy

    You can use this setting to define the system response when a sufficient quantity is available for the order proposal, but requirement quantity optimization cannot use a multiple or discount scale. In this case, you can deactivate the additional restriction check or specify that SAP F&R should calculate an OP quantity that is as close to the additional restriction as possible (but below it) , as close to the additional restriction as possible (but above it), or as close to the mean value of the multiple or discount scale range as possible.

Restriction Check after OP Processing in an OPM Workbench

After you create or change the order proposal in the Replenishment Workbench or Product Workbench, SAP F&R checks all the defined restrictions. The workbench shows whether or not the order proposal meets the restrictions. If you use discount scales as an additional restriction, you can display the scale conditions in the restriction profile view. Note that the system does not optimize the order proposal with regard to fulfilling the defined restrictions, however.
