Symptoms

On :  12.1.3 version, Memory Based Planner in PROD:

Users are on 12.1.3 and have applied 12.1.3.9.2 VCP patch 22706126.  They are running an unconstrained ASCP plan and find that intemittently, there are items with the same exact lead times, intransit and no compression with different sugg due dates but the same sugg start date.  The start dates are later than the anchor date of the plan and they all come from the same source organization and have the same intransit time and they use daily buckets only in the plan options Aggregation tab.  Example data:

All 3 items are buy items

Org = 10:220
Item = G042545-016-140
Proc LT = 3
Post Proc LT = 1
Intransit 45 days - using 24x7 calendar
PTF 37 days

There's a planned order qty = 86 due 30-MAY-2018, Sugg Dock Date = 29-MAY-2018, Sugg Start Date = 10-APR-2018

Org = 10:220
Item = H001742-016-140
Proc LT = 3
Post Proc LT = 1
Intransit 45 days - using 24x7 calendar
PTF 37 days

There's a planned order qty = 46 due 31-MAY-2018, Sugg Dock Date = 30-MAY-2018, Sugg Start Date = 10-APR-2018

Org = 10:220
Item = J000203-016-147
Proc LT = 3
Post Proc LT = 1
Intransit 45 days - using 24x7 calendar
PTF 37 days

There's a planned order qty = 120 due 29-MAY-2018, Sugg Dock Date = 29-MAY-2018, Sugg Start Date = 10-APR-2018

All 3 planned orders have the same Sugg Start Date but different Sugg Due Dates.  The anchor date of the plan is 05-APR-2018 so no planned order is being compressed.  The plan is unconstrained.  The intransit calendar is 24x7.  Notice all of these items have the exact same setup for lead time and PTF and intransit.  Thjs problem comes and goes when rerunning the plan

EXPECTED BEHAVIOR
-----------------------
Expected the Sugg start dates to be different, in this case expected them to be 10, 11 and 12-APR-2018 respectively

STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Run unconstrained ASCP plan
2. Review Supply Demand output in the ASCP workbench
3. Intermittently find items with same exact setup with different planned order due dates having the exact same sugg start date
