•Available-to-Promise (Lze slíbit)
•Capable-to-Promise   (Možné slíbit)
•
•ATP – based on the inventory reservation system – performing the availability check  (calculation
of the date of delivery )
•
•CTP –   based on WHAT IF  scenarios.  Earliest date in which an item will be available
•
•       If no items that can be available, no inbound orders- purchase, transfer , return,
production – it calculates Earliest Date, creates Order lines, and reserves the inventory.
•
•      Maybe integrated to the production scheduling, transfer and   purchase

•Calculation
a)Navision calculates earliest  PDD taking into account inventory
•        availability without customer´s requirements
•
b)Navision verifies, if by hand entered RDD is realistic
•        taking into account inventory availability (backward calculation)

ATP –CTP – Order Promising Setup
•
•The field Offset time – Kompenzace(čas)  contains the period of time that the program must wait
before
• it is allowed to issue a new Purchase Order, Production order or Transfer Order.
• The period starts with the current date.
•
•The time units of measure that you can use are days, workdays, weeks, months, quarters or years.
In the setup for  2018|2019 course was Plánování,
but better to get Purchase order to change to Pož
(Request)

New Item X3
In the setup for  2018|2019 it was 4D
In the setup for  2018|2019 it was 2D

Purchase Item X3 by use of Item journal
Availability by period


ATP –CTP – simple example
(Sales Order)
•Output
•Warehouse
•Handling Time=OWHT
•On the customer Card ST=1D and Shipping agent ST  =   3D   (Shipping agent setup has a priority
over Customer ST=1D). Create new Shipping agent method EXTRA =ESF transport =3D and overwrite again
shipment time on Customer card to 1D only

ATP –CTP – simple example Lze (ATP) with LT=2D
6.2.- 31.1. = 6D = 2D LT + 1D SLT+ 1D  IWHT+ 2D OWHT
10.2.-6.2.  = 4D = 3 ST + 1D  IWHT
IWHT   =   Inbound Warehouse Handling Time  - čas naskladnění
OWHT =   Outbound Warehouse Handling Time – čas vyskladnění
LT         =   Lead Time – průběžný čas
SLT       =  Safety Lead Time – bezpečný průběžný čas
ST         =  Shipment Time – čas dopravy

ATP –CTP – simple example
4.12-2009 – 31.11.2009 = 4 DAYS = 1D  SLT + 2D IWHT +1D OWHT + 7D  LT
8.2.-4.2.=4 D = 3 ST + 1D OWHT
 and change of lead time to 7 D on item card X3
IWHT   =   Inbound Warehouse Handling Time  - čas naskladnění
OWHT =   Outbound Warehouse Handling Time – čas vyskladnění
LT         =   Lead Time – průběžný čas
SLT       =  Safety Lead Time – bezpečný průběžný čas
ST         =  Shipment Time – čas dopravy
Shipping time of shipping agent>higher
priority than ST on Customer card.
