For Some Items Projected Available Balance (PAB) is Below Safety Stock (SS) For Several Months Out In The Plan Horizon When Planning Time Fence (PTF) Is Only 1 Day (Doc ID 2568678.1)

Last updated on AUGUST 19, 2019

Applies to:

Oracle Materials Requirement Planning - Version 12.2.6 and later
Information in this document applies to any platform.

Symptoms

On : 12.2.6 version, Materials Requirements Plan In PROD

For a particular buy item users have defined
PTF = 1 day
Hard SS = 522

They are running a regular MRP plan and have several demands and supplies including Purchase Orders (PO's) already created.  They notice that with a plan run date in early May 2019 that PAB is below SS until early July and they don't understand why planned orders are not being generated to cover SS until almost 2 months later since PTF for the item = 1 day

EXPECTED BEHAVIOR
-----------------------
Users expect SS to be covered by planned orders when PAB goes below SS

STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Create Hard SS for an item
2. Create Supply Demand for the item
3. Run MRP plan
4. Find that for several months PAB is below SS for an item
