> Here are high level design notes to based on the requirement specified under OFBIZ-7355 to support the product level replenishment from any inter-company facility before raising the ordering from an outside vendor.
> * We could extend the MRP logic (MrpEvent,Requirenent) to honor these new types and create corresponding event & requirement for Stock transfer between facilities.
> * Introduce two new entities ProductFacilityAssoc & FacilityAssocType and use them in conjunction with MrpEventType and corresponding RequirementType to serve the requirement for replenishing the store's via Inter-facility transfers mode.  The data model & UI could be extended as follows:
> {code}
> <!-- New Entity ProductFacilityAssoc (Product-wise associations between facilities to define from what all facilities a given product can be replenished)-->

> {code}
> MRP engine would start creating event beginning with store's primary facility based on set RMEI under ProductStoreFacility e.g, XFERRQM_STOCK_ATP for StoreWarehouse_01, In other words if MinStock < ATP , then MRP algorithm would: 
> # Look up and consume the respective ATP from all the eligible "facilityIdTo" (based on ProductFacilityAssoc), from where given product is transferable. Based on their priorities start allocating ATP unless it meet the (MinStock-ATP) requirement for a given store e.g., 'StoreWarehouse_01' .
> # Create new MRP Event with Event type "PROP_ATP_STOCK_TRANSFER" with Proposed Quantity = MINIMUM STOCK - ATP from the facility (with highest priority i.e.,RegionalWarehouse_01) to the destination facility.
> ## If demand for (MinStock-ATP) is still not fully met by any facility with higher priority then repeat step#1 for all the associated facilities in descending order of priority unless ATP from all eligible facilities is exhausted.
> # Based on above MRP Event Type and proposed quantity, In turn create the new Requirement with type TRANSFER_REQUIREMENT between originating and destination facility.
> # Over Requirement screen (UI) we can provide the "Transfer" button against all the requirement with type TRANSFER_REQUIREMENT
> # On hitting the "Transfer" button, The new 'Stock Transfer' requests could be created for a product between eligible facilities based on above step. 
> # The created Stock Transfer request can be completed by shipping and receiving given product from originating facility and destination facility respectively.
