| # Items - Purchase Business Partner (tdipu0110m000) Item-supplier information becomes relevant to Enterprise Planning, if you generate planned purchase orders. Enterprise Planning always searches for item-supplier information. If the item-supplier information is not available, Enterprise Planning generates the order without business partner. The following table explains some of the parameter settings in the Items - Purchase Business Partner (tdipu0110m000) session.
Item – Purchase Business Partner
Field | Description
--- | ---
Item | The item segment of the plan items to which this record applies. All plan items with the same item code as the item code in the item supplier information, can use this record. In this way, there can be a one-to-many relation between plan item and item-supplier information.
Item Group | You can leave the item code empty and fill this field. In this way, you can define the item-supplier information on two levels: item and item group. Enterprise Planning always searches for the item level first and then for the item-group level.
Ship-from Business Partner | The business partner from where the ordered item is shipped. Note: if the warehouse in the Ship-from Business Partners (tccom4521m000) session is not equal to the warehouse on plan item data, this supplier is ignored. An empty warehouse for the ship-from business partner means the business partner can deliver to any warehouse.
Effective date and expiry date | The dates between which the record is effective. If the supplier is not effective, LN does not consider the supplier during simulation.
Preferred | The preferred supplier among a group of alternative suppliers. At any single time, only one item supplier can be the preferred supplier.
Status | This field indicates whether the supplier is blocked.
Priority (Sourcing tab) | LN uses the priority of the item-supplier record for the supplier choice during the order generation process. Zero is the highest priority, 999 is lowest priority.
Sourcing Percentage (Sourcing tab) | LN uses the sourcing percentage of the item-supplier record for the supplier choice during the order generation process. The sourcing percentage is always used as a relative percentage compared to the other item supplier records with the same priority
Order Quantities (Ordering tab) | Each item-supplier record has its own order-quantity settings. Enterprise Planning applies the rules of the most detailed level. The order-quantity settings fulfil the same role as the order-quantity settings on Item Ordering level.
Carrier (Receiving tab) | Determines the transportation time that is used for the lead time calculation of the planned order.
Lead Time Horizon | Determines the date from where the planning of the order lead time is done. Planning is done only on the calculated lead time and not the individual lead-time components. The use of a lead-time horizon saves system performance of the order generation process. This horizon fulfills the same role as the fixed-lead-time horizon in Enterprise Planning for planned production orders.
Calculated Lead Time (display only) | The calculated lead time that represents the lead time components. The calculated lead time is a combination of internal processing time, safety time, supply time, transportation time and warehouse inbound time. The calculated lead time fulfills the same role for planned purchase orders as the order lead time on plan item data for planned production orders
Supplier Capacity (Shipments tab) | Reflects what the supplier can ship during a predefined span of time. The supplier capacity is a constraint for order generation. When the total supply of all the orders that were generated for this item-supplier combination within the capacity time unit exceeds the capacity, Enterprise Planning generates no more orders. The constraint is not only determined by the supplier capacity, but also by the maximum capacity tolerance.
Maximum Capacity Tolerance | Tolerance that indicates how far the supplier capacity can be exceeded for order generation. The constraint for order generation is thus determined by the following formula:
    ∑ (order quantities of all supply orders) per capacity time unit ] <= [ Supplier capacity * (1 + Maximum Capacity Tolerance/100)
Capacity Time Unit | Defines the bucket length for supplier capacity. LN calculates the bucket start dates starting from the scenario start date
