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. |
