EDD Classic Constrained Plan Reschedules Out Existing Work Order And Recommends New Planned Order In Its Place (Doc ID 2421435.1)

Last updated on JULY 10, 2018

Applies to:

Oracle Advanced Supply Chain Planning - Version 12.2.5 and later
Information in this document applies to any platform.

Symptoms

On : 12.2.5 version, Memory Based Planner in Test

Users are on 12.2.5 and have applied 12.2.5.2 patching. They've also applied CUM #16 patch 27575064 on top of 12.2.5.2. They are running an EDD Classic Constrained Plan and constrained only against resources. However they notice that while there is a non firm wip job that is past due the plan reschedules it out into the future about a month and creates new planned orders inside the WIP job unexpectedly. If they run an unconstrained plan the wip job is scheduled before the planned orders as expected. Example data from Constrained plan:

Plan = WBY-CON - plan id = 2021
Item name = 01CVS100TT144 - item id = 7
Org code = PLD:WBY Org id = 85
Var LT = 0.000015 - currently
Min Ord Qty = 3000
Max Ord Qty = 80000
Fixed Days Supply = 20

What they see is in the Constrained plan for the item, plan run date = 07-JUN-2018. This plan pushed out the wip job qty = 21998 from past due date in April out to 23-JUL-2018 period while at the same time created planned orders qty = 22819 on the anchor date of the plan 07-JUN-2018 inside the wip job. The unconstrained plan has the wip job on the anchor date of the plan an the planned orders pushed out to Aug 2018 period

EXPECTED BEHAVIOR
-----------------------
Existing wip job supply should be consumed first before creating new supply planned orders.

STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Run EDD Classic Constrained Plan
2. Review Supply Demand in ASCP workbench
3. Find items where wip jobs are pushed out into the future and planned orders planned before the wip jobs
4. Problem does not occur in unconstrained plan
