Applies to:

Oracle Advanced Supply Chain Planning - Version 12.1.3 and later
Information in this document applies to any platform.


On : 12.1.3 version, Constrained Planning in All Instances

Users are on 12.1.3 and have applied VCP Patch 14247039. They're using 64 bit Linux MBP and have MSONWL64.ppc 120.3.12010000.250.1201140.12 from one off patch 22112974. Users run EDD Constrained Without Detailed Scheduling Plan. They're seeing intermittent issues where Planned Orders start date 1 day earlier than the Demand due date even though the time involved should be less than one day. Other planned order are starting/finishing for the same item/org on the same day as expected. Example data:

Item = SO10149

There's a planned order qty = 1 with Sugg Start Date = 14-SEP-2016 and Sugg Due Date = 15-SEP-2016 (Trans id = 445996187) - The resource hours show 4 x 0.007404 hours = 0.029616 - This can easily be done on same day so why 1 day difference? Also note there's a planned order for same item qty = 650 with same start and due date = 12-SEP-2016 - this is what is expected (trans id 445996186)

Expect to see correct start and due dates to be the same since the lead time of the item is less than 1 day

Things tried:
Support found lead time rollup was not done for this routing, so that was done and confirmed and the changes collected. However the results are still the same

The issue can be reproduced at will with the following steps:
1. Run EDD Without Detailed Scheduling Plan
2. Observe Suggesting Planned Orders start date 1 day earlier than expected vs actual Demand due date. They want to build and ship on same date, not a day earlier
