| # Supply chain modeling Supplying Relationships (cprpd7130m000) The supplying relationships model the distribution structure for Distribution Requirements Planning (DRP). Supplying relationships model a plan item relation and not a location-to-location relation. The plan item itself defines the location by the cluster code and the default warehouse of the plan item. You can define supplying relationships on these levels: Plan item Cluster Item group Enterprise Planning searches for supplying relationships on each level (first on plan item level, then on cluster level, and so on) until an applicable supplying relationship is found. Capable-to-Promise (CTP) checks are also performed by using supplying relations but never more than only one level deep. The following table explains some of the parameter settings in this session.
Supplying relationships
Field | Description
--- | ---
Supplying Site | Defines the site were the supplying item is defined. You can define a supplying relationship over multiple sites.
Effective Date and Expiry Date | Determine if the supplying relation can be selected for order generation.
Supply Costs | Enterprise Planning uses the supply costs for the supplier choice when a supply strategy is defined for an item. The supply source can be determined at least costs.
Percentage | This field is used as a relative percentage in the supply allocation
Priority | This field is used to order the supplying sources based on the priority rules as defined in the supply strategies.
Supply Resource, Supply Lead Time and Carrier | These fields are used for lead-time calculations.
Supply Lead Time | The transportation time from supplying warehouse to the receiving warehouse.
Carrier | The carrier responsible for moving the goods between the supplying and the receiving warehouse.
Minimum Volume | This field is used in the process of assigning planned supply to this supply source.
Maximum Volume | The maximum is a hard constraint. When the total amount of supply that is generated for this supplying relation meets the maximum volume, no further supply can be generated. Note that this constraint is not bound to a time unit, but is valid for the whole time between effective and expiry date (total amount of supply = planned orders, interplant planned distribution orders, adjustment orders (cycle counting), transfer orders, assembly orders)
Maximum Days Overdue | The number of days that a supplying relation can be selected before or after the planned finish date.
