| Overview of purchase schedule handlingA purchase schedule is a timetable of planned supply of
materials. Purchase schedules support long-term purchasing with frequent
deliveries and are usually backed by a purchase contract. All requirements for
the same item, buy-from business partner, ship-from business partner, purchase
office, and warehouse are stored in one schedule. Purchase schedules are used
instead of standard purchase orders in cases where full visibility and time
phasing of material requirement information is required. Therefore, purchase
schedules provide a more detailed way to specify the delivery dates/times per
item. The following types of purchase schedules exist: Push schedule A list of time-phased requirements, generated by a central
planning system, such as Enterprise Planning or Project that is sent to the purchase business partner. Push schedules contain both a
forecast for the longer term and actual orders for the short term. A push
schedule is a nonreferenced schedule. Pull forecast schedule A list of time-phased planned requirements, generated by Enterprise Planning, that is
sent to the purchase business partner. Pull forecast schedules are only used
for forecasting purposes. To order the items, a pull call-off schedule must be
generated with the same schedule number as the pull forecast schedule. Similar
to a push schedule, a pull forecast schedule is also a nonreferenced schedule. Pull call-off schedule A list of time-phased specific requirements of purchased items,
triggered from Assembly Control, or Warehousing (KANBAN, Time-phased order point). A pull call-off schedule
is a referenced schedule.

- Set up a segment set as follows: For more information, refer to Using segment sets.
- Specify patterns in the Patterns (tcccp0690m000) session.

- The purchase schedule related parameters that apply to an
item and business partner combination in the Purchase Contract Line Logistic Data (tdpur3102m000) or Items - Purchase Business Partner (tdipu0110m000) sessions.
- Store delivery patterns by warehouse, buy-from business
partner/ship-from business partner and item in the Delivery Patterns by Warehouse / BP / Item (tdipu0124m000) session. Based on the combinations
in this session, planned delivery moments can be generated in the Generate Planned Delivery Moments (tdipu0225m000) session.
- Generate planned delivery moments in the Generate Planned Delivery Moments (tdipu0225m000) session
to determine when an item can be delivered. The dates returned, listed in the Planned Delivery Moments (Shipment Based) (tdipu0125m000) and Planned Delivery Moments (Receipt Based) (tdipu0126m000) sessions, are used by Enterprise Planning for lead
time offsetting.
