Symptoms

On : 12.2.5 version, Constrained planning in PROD:

Users are on 12.2.5 and have applied patch 22493520 Mandatory 12.2.5 VCP Consolidated Patch 2 - also have applied cum 3 patch 24960243 on top of 12.2.5.2 - They are running an EDD Constrained Without Detailed Scheduling ASCP plan. Users are also using Project/Task and have enabled Use Common Supplies For Demands in the Plan Options.  They are finding the following issue:

Common On hand is not pegging to demands in chronological sequence. Example data:

Org = PRD:DE1 org id = 151
Item = 117W6872P001 = inv item id = 57375
On hand qty = 11 has no project/task

Project/Task
DER1-879413 / 32162491
Pre Proc LT = 5
Proc LT = 120
Post Proc LT = 10
FDS = 5

On hand qty = 11 and is not attached to project/task - it pegs to demand on 02-AUG-2017 then jumps over several demands from 03-07-AUG and starts pegging again to demands on 08-AUG-2017 and then further in the future.

Some setup details as this is Project-Task environment
===============
Reservation and Hard Pegging Level = Project-Task
Apply Order Modifiers at Hard Pegging Level
Enabled use Common Supplies for Project Demands

Setting profile option MSC: Minimize changes to chronological sequence of supplies = Yes and rerunning the plan does not fix either issue

EXPECTED BEHAVIOR
-----------------------
A. Expect on hand to peg to earliest demands until exhausted and not skip over demands to satisfy future demands
B. Expect earliest due PO's to be pulled in first before considering to pull in future PO's

STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Run EDD Constrained without detailed scheduling ASCP plan
2. Review ASCP workbench supply demand output
3. See where item on hand skips over certain demands in pegging and also see future PO's rescheduled in and early PO's rescheduled out
