Service - Inventory Manager

Overview

Each inventory type is handled by a Service - Inventory (handlers) service.

The specific identification method is used for accounting and tracking individual units of inventory, this applies COGS individually to each unit and allows for transparent supply chain at a per unit level. Fractional selling of units is not allowed, so when inputting inventory should input at the smallest divisible unit it can be sold at.

The Inventory Manager service handles detail shared by all Inventory Handler services.

• Describes an inventory descriptor, or SKU, interchangeable units (fungible) are classified under the same inventory instance

inventoryUnit

{
	objectType: "inventoryUnit",
	canDelete: false,
	belongTo: { 
		serviceTag: "Business",
		objectType: "business"
	},
	addOnDataStructure: [],
	storageResources: {
		myGraph: {
			storageType: "graph",
			graphServerTag: "GraphHandler"
		},
		dynamoDB: {
			storageType: "dynamoDB",
			"tableName": "inventoryUnit",
		}
    },
    fieldNames: {
		inventoryUnitId: {
			type: "string",
			randomOnCreate: true,
			storageResourceTags: ['myGraph', 'inventoryUnit']
		},
		cost: { // sums all costs, or COGS for the unit
			type: "numeric", 
			storageResourceTags: ['myGraph']
		},
    },
    identifiers: [
		{
			type: "identifier",
			fieldName: "inventoryUnitId"
		}
    ]
}

• A single unit of inventory
• Use dynamo table to perform actions such as reserving the unit to a unique flow which moves it's location before releasing the reservation
