Service Parts Planning (SPP): Fixed Days Supply (FDS) Not Being Honored In Unconstrained Plan (Doc ID 2445239.1)

Last updated on AUGUST 19, 2019

Applies to:

Oracle Service Parts Planning - Version 12.2.4 and later
Information in this document applies to any platform.


On : 12.2.4 version, Memory Based Planner in Test:

Users are on 12.2.4 and have applied VCP Cum Patch - 19549533 - using 64 bit Linux MBP with version - MSONWL64.ppc 120.15.12020000.20.1202040.3 from one off patch 20300079 back in 2015 - some key profiles

MSC: Split Planned Orders for Scheduling Flexibility = No
MSO: Split Planned Orders for Assigned Units = Yes - this is for optimized plans only
MSC: Split Planned Order to perform safety stock pegging = 1 = No

Users are running an SPP plan and they are NOT enforcing constraints. They are testing out using Fixed Days Supply (FDS). However the plan output does not honor the FDS. Example data:

item = 14011AMS-524 - inv item id = 19794
Org = PRD:APP Org id = 103
FDS = 32
FLM = 70
There are 66 Planned new buy orders all qty = 1 on the anchor date of the plan 13-AUG-2018 with trans id from 13121106 to 13121095 - these are all to satisfy Non-standard job demand also on same anchor date. Then there's another Planned New Buy Order qty = 101.6 that's due 30-AUG-2018 and this satisfies only forecast qty = 101.6 due on 30-AUG-2018 (trans id = 13121090) and qty = 36 due on 30-AUG-2018 (trans id = 13121089). There are more Planned new buy orders in September and beyond that do not honor the FDS = 32 days

Users tried adding a simulation set to make it work but that didn't work either. Supported tested internally and that appears to be honoring FDS as expected

Expect FDS order modifier to be honored in the plan output

The issue can be reproduced at will with the following steps:
1. Add FDS days in item attributes and collect data
2. Run SPP plan and FDS is not honored
3. Try again using simulation set and attach to plan and run it
4. FDS still not honored
