| # Distribution lead time based on the supply calendar In Enterprise Planning, the supply lead time for a planned purchase order consists of the following lead times: The internal processing time from the Items - Purchase Business Partner (tdipu0110m000) session. The supply time from the Items - Purchase Business Partner (tdipu0110m000) session. A transport time between the address of the ship-from business partner and the receiving warehouse, based on a relevant distance table (if available) in the Distance Table by City (tccom4137s000) session or the Distance Table by ZIP Code/Postal Code (tccom4138s000) session The safety time from the Items - Purchase Business Partner (tdipu0110m000) session. The sum of these lead times is displayed in the Calculated Lead Time (Days) field in the Items - Purchase Business Partner (tdipu0110m000) session. In addition, the inbound lead time from the Warehouse - Item (whwmd2110s000) session is used. Using the calculated lead time If the order's finish date falls outside the lead-time horizon (defined in the Items - Purchase Business Partner (tdipu0110m000) session), then the start date is computed by: Planning backward the inbound lead time using the calendar of the item/warehouse combination (see the Warehouse - Item (whwmd2110s000) session). Subtracting the cumulative lead time from the resulting date. Example: purchase lead time based on the calculated lead time
CLT | Calculated lead time (from the Item - Purchase Business Partner (tdipu0110m000) session
ILT | Inbound lead time (from the Warehouse - Item (whwmd2110s000) session).
O/S/E | Outbound lead time / Safety time / Extra lead time.
A | Start date
B | Finish date
C | Requirement date
Using planned lead times If the order's finish date falls within the lead-time horizon, the supply lead time is determined by planning backward each lead time separately: The inbound lead time is planned using the calendar of the item/warehouse combination (see the Warehouse - Item (whwmd2110s000) session). The supplier safety time is not planned with a calendar, but is interpreted as a number of calendar days. The transport time is planned using the calendar linked to the address of the ship-from business partner. The supply time is planned using the calendar linked to the address of the ship-from business partner. The internal processing time is planned using the department calendar of the purchase office defined for the item/business partner combination. Example: purchase lead time based on planned lead times
IPT | Internal processing time (from the Items - Purchase Business Partner (tdipu0110m000) session).
SuT | Supply time (from the Items - Purchase Business Partner (tdipu0110m000) session.
TrT | Transport time (based on distance table).
SST | Supplier safety time (from the Items - Purchase Business Partner (tdipu0110m000) session).
ILT | Inbound lead time (from the Warehouse - Item (whwmd2110s000) session).
O/S/E | Outbound lead time / Safety time / Extra lead time.
A | Start date
B | Finish date
C | Requirement date
No supplier If no supplier can be found, Enterprise Planning uses the following data to compute a supply lead time: The inbound lead time from the Warehouse - Item (whwmd2110s000) session, using the calendar of the item/warehouse combination. The supply time from the Items - Purchase (tdipu0101m000) session, interpreted as calendar days. Example: purchase lead time without supplier
SuT | Supply time (from the Items - Purchase (tdipu0101m000) session).
ILT | Inbound lead time (from the Warehouse - Item (whwmd2110s000) session).
O/S/E | Outbound lead time / Safety time / Extra lead time.
A | Start date
B | Finish date
C | Requirement date
