Purchase order lead time
The following tables list the lead time components, the calendar, and availability type that are used to plan the purchase order lead times.
Lead time component (detailed planning: with supplier, within lead time horizon) | Sequence to find calendar code | Sequence to find availability type (AT) |

Calculated lead time (BP) | Company | Purchase Parameters |
-
The BP safety time, that is part of the supply time (BP), is calculated using the time zone and the calendar code of the current company. The above described fallback logic is disregarded.
-
You can use the company calendar for the planning of purchase orders with customer furnished materials, as no supplier is involved in delivery of having materials from your customer.
Lead time component (no supplier) | Sequence to find calendar code | Sequence to find availability type (AT) |

Supply time (item) | Company | Purchase Parameters |
Planned purchase orders are planned in the same way as actual purchase orders (the same algorithm is used). A purchase order can be planned as follows:
- With supplier, within lead time horizon
- With supplier, outside lead time horizon
- Without supplier
The lead time horizon is planned forward from the current date. In other words, the date of the order planning run, using the company calendar.
With supplier, within lead time horizon
The internal processing time, the time required to ship an order, uses the purchase office calendar. If this calendar is not defined, the company calendar is used.
Supply time and supplier safety time do have a three-level fallback mechanism:
- Ship-from business partner calendar
- Buy-from business partner calendar
- Company calendar
For more information on transportation time, refer to Transportation time.
Without supplier
If no supplier is present, you can use the company calendar to plan the item supply time.
