> Here are the most common set of business requirement to support product level replenishment
within a given facility(store/warehouse) via any inter-company facility (preferred warehouse/stocking
facility) before raising the purchase order from an outside vendors/suppliers.
> In current standard OFbiz workflow there are essentially two basic types of material
requirements generated at product-facility level. Both of these can be created manually or
could be suggested by MRP engine:
> * First, is "Product Requirement" which suggests that the given product is going to be
low or out of stock within any given facility in a given time frame based on upstream demand
signals within the supply chain and hence can more commonly be treated as Purchase Requirement
that need to be eventually transformed as Purchase Orders to be raised from a given vendor/supplier
> * Second, is "Internal Requirement" which suggests that the given product is going to
be low or out of stock within any given facility in a given time frame based on upstream demand
within the supply chain. But such products can be internally manufactured(produced) and hence
can more commonly be treated as Production Requirement that need to be eventually transformed
as Production Order (Production Run).
> *Gap*
> Currently the OFbiz planning algorithm (aka MRP) generate the requirement by only considering
the supply available within the given facility. But there is no planning logic built into
the system which can support and look up the supply availability in a complex supply chain
setup where business could be run using multiple facilities spread geographically. A more
common examples could be brick and mortar retail stores chain having multiple stores spread
across geographically. Or any manufacturing business that own multiple production facilities
and warehouse spread across geographically. 
> *Requirement*
> There are many instances, where material visibility in a multi-facility setup within
an organization or company is not very accurately gauged. We would need to start building
an intelligent planning system that could gauge such material availability across facilities
and honor them while furnishing the requirements around any product within any given facility.

> Let's consider following use case (Please refer to attached screenshot for reference)
> !screenshot-1.png|width=800px!
> :
> * A retail chain has multiple stores and say a given physical store 'Store_01' and is
strategically located near two warehouse in the region say Whse_01 & Whse_02, 
> * One centralized warehouse(Main/buffer) say 'Backup_Whse' that supplies material to
all the stores and regional warehouse 
> * Any retails store e.g. Store_01 shouldn't raise purchase order from any outside vendor
directly.
> * As Store_01 is strategically located near Whse_01 & Whse_02, so system should always
suggest to replenish any product shortfall by first looking up and pulling up available supply
from Whse_01 & Whse_02 and then from Backup_Whse in that order of priority.
> * Banckup_Whse mostly works on push system and supplies the products to all regional
warehouse and physical stores.
> Now we could design an OFbiz based replenishment planning that :
> * Could allow to associate and rank the facilities(physical store/warehouse) that could
replenish the material at any other facility (physical store/warehouse)
> * Could suggest the "*Transfer Requirement*" by gauging the product shortfall within
any given facility product-facility at any given point of time by
> * Could allow to configure and manage the setting at facility(ProductStore or ProductFacility)
level, to let planning engine know whether given facility could replenish stock via Transfer
Requirement from any other facility. If not then it could take normal route of replenishment
via Purchase Order or Production Order route.
