How OSP Requisition Need by date defaults

OSP Requisition need by date generates based on OSP item lead time setup.
OSP Items can be planned with Fixed & Variable lead times, asper this setup OSP Requisitions need by date varies.

Lets say OSP Item unit type is Assembly in item master

Now lets see how these Lead times would work..

Scenario-1 : Irrespective of OSP item quantity on OSP Requisition/po , vendor processing time must be 15 days

Setup :-

Fixed Lead time @ Org is 15,
Variable lead time setup as Zero

When requisition created for lets say 30 qty..rule will be applied like this

Need by date = Operation start time + [Fixed lead time + (Variable lead time * OSP Item qty)]

so Need by date = Op start time + 15 + (0*30) = OSP op start time + 15 days


Scenario-2 : Irrespective of OSP item quantity on OSP Requisition/po , vendor processing time must be as SETUP TIME 10 days & 2 days PROCESSING TIME per unit.

Setup :-

Fixed Lead time @ Org is 10,
Variable lead time setup as 2

When requisition created for lets say 20 qty..rule will be applied like this

Need by date = Operation start time + [Fixed lead time + (Variable lead time * OSP Item qty)]

so Need by date = Op start time + 10 + (2*20) = OSP op start time + 50 days

Hope this helps.
