On : version, Constrained Planning In All Instances:

Users are on 12.1.3 and have applied VCP Patch 17350769. Using 64 bit Linux MBP MSONWL64.ppc 120.3.12010000.471 which can only come from one off patch 21146727:R12.MSC.B. Users run EDD Classic Constrained Plan. What they're seeing is planned orders being generated too soon making PAB way above safety stock for no known reason. Example

Item = 1E49331H01
Proc = 14
Post Proc = 5
Fix LT = 10
FLM = 200
FDS = 20
Min Ord Qty = 200
SS Method = MRP Planned Percent
SS Days = 20
SS % = 1500

Plan options - PTF, APO DTF - Peg Supplies by Demand Priority - Overwrite = None - All Planned Items - Dem Pri Rule - Sales orders, forecast, SS and then request date - 30/32/4 - EDD Classic all days 30 - Use end item substitution

Qty = 200 planned order due 05-OCT is way too soon. Didn't need it until 02-NOV-2015. On this date 05-OCT
PAB = 501
SS = 163

If I remove the qty 200 planned order my PAB would still be way above SS at 301 vs SS at 163


MSC: Include Safety Stocks in Priority Based Pegging = Yes
MSC: Split Planned Order to perform safety stock pegging = 2 = Yes but do not violate order modifier
MSC: Split Planned Orders for Scheduling Flexibility = No
MSO: Supplies used for satisfying transient safety stock = 1 = Supplies pegging to lower priority demands
MSO: Net All Firm Supplies Before Creating Planned Order = 1 = All Supplies

ASCP should not create planned orders many months in advance when there are on hand available

The issue can be reproduced at will with the following steps:
1. Advanced Supply Chain Planner Responsibility
2. Nav: Supply Chain Plan -> Launch Plan
3. View Plan results in Planners Workbench
