| Determining the planned receipt dateIf you enter a purchase
order line or purchase schedule line, you must also calculate a planned receipt
date. The planned receipt date is calculated based on the order or generation
date, the item lead times, and the horizon. Dependent on the horizon, the
planned receipt date can be accurately or globally determined. Note Item lead times can be specified in the Items - Purchase Business Partner (tdipu0110m000) and Purchase Contract Line Logistic Data (tdpur3102m000) sessions. The horizon is calculated from the Lead Time Horizon (Days) field in the Items - Purchase Business Partner (tdipu0110m000) or Purchase Contract Line Logistic Data (tdpur3102m000) sessions. To calculate the planned receipt date, choose Calculate in the Purchase Order Lines (tdpur4101m000) session or Purchase Schedule Lines (tdpur3111m000) sessions. LN shows the planned
receipt date in the Planned Receipt Date field of these sessions. Determining the horizon LN determines the horizon by adding the lead time horizon to the current date and
time taking into account the company calendar to which the purchase availability type is linked. LN compares the
order/generation date with this horizon, which results in one of the following
possibilities: - The order/generation
date lies beyond the horizon. Therefore, the planned receipt date is globally
determined.
- The order/generation
date lies within the horizon. Therefore, the planned receipt date is accurately
determined.
Note - The lead time horizon
is always expressed in days.
- The company calendar
is the calendar that is linked to the company in the Companies (tcemm1170m000) session.
Example horizon determination Current date/time: Wednesday, March 10/15:00:00 | The company calendar for the Purchase Control availability type has an 8:00:00 start time and a 16:00:00 end time and is
available from Monday through Friday each week | Lead time horizon (in days): 10 |
Because on Wednesday one hour is available, Wednesday counts for
a whole day. So, during the first week three days are available. During the
next week five days are available. So, two days are left for the third week.
Because LN finds time
available on Tuesday, March 23, this day counts for a whole day and LN takes the last
available time as the horizon time. So, the horizon is Tuesday, March
23/16:00:00. Order/generation date beyond horizon If the order date lies
beyond the horizon, LN considers the purchase order/schedule as forecast demand for which no accurate
determination of the planned receipt date is yet required. LN determines the planned receipt date as
follows, taking into account the company calendar:
Order/generation date + calculated lead time
LN retrieves the calculated lead time from
the Calculated Lead Time (Days) field of the Items - Purchase Business Partner (tdipu0110m000) or Purchase Contract Line Logistic Data (tdpur3102m000) session. Note - The calculated lead
time is always expressed in days.
- Before the company calendar's start date and after the
company calendar's end date, LN uses the standard calendar.
Example order/generation date beyond
horizon Order/generation date: Thursday, March 25/17:00:00 | Calculated lead time (in days): 5 | The company calendar for the purchase availability type has an
8:00:00 start time and a 16:00:00 end time and is available from Monday through
Friday each week. |
Because Thursday, March 25/17:00:00, is not an available
date/time according to the calendar, LN searches for the first available date/time
to which the calculated lead time must be added, which is Friday, 26/8:00:00.
So, four days are left for the next week. Because LN finds time available
on the fourth day, Thursday, April 1, this day counts for a whole day and LN takes the last
available time as the planned receipt date. So, the planned receipt date is
Thursday, April 1/16:00:00. Order/generation date within horizon If the order/generation
date lies within the horizon, LN considers the purchase order/schedule as immediate demand for
which an accurate determination of the planned receipt date is required.
Therefore, LN determines the planned receipt date by adding up the lead time components,
taking into account the related calendars for each
component. LN determines the planned receipt date as follows:
Order/generation date + internal processing time + supply time + transportation time + safety time.
LN retrieves the order/generation date and the lead time components as follows: - Order date from the Order Date field in
the Purchase Order Lines (tdpur4101m000) session.
- Generation date from the Generation Date field in the Purchase Schedules (tdpur3110m000) session.
- Internal processing time from the Internal Processing Time field in the Items - Purchase Business Partner (tdipu0110m000) session or Purchase Contract Line Logistic Data (tdpur3102m000) session.
- Safety time from the Safety Time field
in the Items - Purchase Business Partner (tdipu0110m000) session or Purchase Contract Line Logistic Data (tdpur3102m000) session.
- Supply time from the Supply Time field
in the Items - Purchase Business Partner (tdipu0110m000) session or Purchase Contract Line Logistic Data (tdpur3102m000) session.
- Transportation time from
the Transportation Time (Days) field in the Items - Purchase Business Partner (tdipu0110m000) session or Purchase Contract Line Logistic Data (tdpur3102m000) session.
Calendar search path When determining the planned receipt date, LN also takes into
account the calendars that are related to the lead time components. LN searches for the
calendars that are related to the lead time components as follows: Internal processing time If a purchase office is specified for the item and buy-from
business partner combination and a calendar is specified for the purchase office, LN takes into account
the purchase office's calendar. You can specify the purchase office's calendar
in the Departments (tcmcs0565m000) session. - If no calendar is specified for the purchase office or if no
purchase office is specified, LN takes into account the company calendar.
Supply time If a ship-from business partner is specified and the
ship-from business partner's calendar is specified, LN takes into account
the ship-from business partner's calendar. - If no ship-from business partner calendar is available, LN takes into account
the buy-from business partner's calendar.
- If no buy-from business partner calendar is available, LN takes into account
the company calendar.
Transportation time If a carrier is specified and a buy-from business partner is
linked to the carrier and the buy-from business partner's calendar is known, LN takes into account
the buy-from business partner's calendar. - If a carrier is specified, and a buy-from business partner
is linked to the carrier, but the buy-from business partner's calendar is not
specified, LN takes
into account the company calendar.
- If a carrier is specified, but no buy-from business partner
is linked to the carrier, LN takes into account the company calendar.
- If no carrier is specified, LN takes into account
the company calendar.
Safety time If a ship-from business partner is specified and the
ship-from business partner's calendar is specified, LN takes into account
the ship-from business partner's calendar. - If no ship-from business partner calendar is available, LN takes into account
the buy-from business partner's calendar.
- If no buy-from business partner calendar is available, LN takes into account
the company calendar.
LN searches for the actual calendars based on: - The calendar that is
related to the lead time component.
- The purchase availability type.
- The availability type for carrying goods.
- The calendar's start
date and end date.
Note - You can express the lead
time components in hours and in days.
- You can specify the
purchase availability type in the Purchase Parameters (tdpur0100m000) session.
- You can specify the availability type for carrying goods in the Availability Type for Carrying Goods field in the COM Parameters (tccom0000s000) session.
- Before the applicable calendar's start date and after the
calendar's end date, LN uses the standard calendar.
Example order/generation date within or before
horizon Order/generation date: | Friday, March 12/7:00:00 | Internal processing time (in hours): | 6 | Supply time (in days): | 1 | Transportation time (in days): | 2 | Safety time (in hours): | 4 |
The company calendar for the purchase availability type and
for the Availability Type for Carrying Goods has an 8:00:00 start
time and a 16:00:00 end time and is available from Monday through Friday each
week. The buy-from business partner's calendar for the purchase availability
type and for the Availability Type for Carrying Goods has an 8:30:00 start
time and a 16:30:00 end time and is available from Monday through Friday each
week. The ship-from business partner's calendar for the purchase availability
type has a 9:00:00 start time and a 17:00:00 end time and is available from
Monday through Friday each week. LN determines the planned receipt date as follows: - LN adds the internal processing time to the
order/generation date, taking into account the company calendar. Because
Friday, March 12/7:00:00, is not an available date/time according to the
company calendar, LN searches for the first available date/time to which the internal processing
time must be added, which is Friday, March 12/8:00:00.
- LN adds the internal processing time to
Friday, March 12/8:00:00. The resulting date/time is Friday, March 12/14:00:00.
- LN adds the supply time to Friday, March
12/14:00:00, taking into account the company calendar. According to the company
calendar on Friday, March 12, two hours are left. Because the supply time is
expressed in days, LN considers Friday, March 12, as a whole day. So, the resulting date/time is
Friday, March 12/16:00:00.
- LN adds the transportation time to Friday,
March 12/16:00:00, taking into account the buy-from business partner's
calendar. According to the buy-from business partner's calendar on Friday,
March 12, half an hour is left. Because the transportation time is expressed in
days, LN considers
Friday, March 12, as a whole day. The second transportation day is the first
available day after Friday, March 12, which is Monday, March 15. So, the
resulting date/time is Monday, March 15/16:30:00.
- LN adds the safety time to Monday, March
15/16:30:00, taking into account the ship-from business partner's calendar.
According to the ship-from business partner's calendar, on Monday, March 15,
half an hour is left. The remaining 3,5 hours is added to Tuesday, March 16,
starting at 9:00:00. So, the resulting date/time is Tuesday, March 16/12:30:00,
which is the planned receipt date.
Note If you enter a purchase
order line and no data is specified for an item in the Items - Purchase Business Partner (tdipu0110m000) session, LN determines the
planned receipt date using only the supply time from the Items - Purchase (tdipu0101m000) session. For more information, refer to Determining the planned receipt date based on the supply time only. | |
