Service - Stock Location Manager

Overview

Each Sell Offer (Standard) record points to a Stock Loctation record which is handled by a Service - Stock Location (handlers) service, with Service - Stock Location Standard handling simple quantities remaining in stock per stock location record.

The Stock Location Manager service handles shared orchestration of Stock Location Handler services.

• connects sellOffer to stockLocation

Translate Ids - stockLocation to sellOffer

• from stockLocationId to sellOfferIds

Complex Filter requests

• Not yet used at the Manager level, would send requests to all handlers, could perhaps setup to automatically pass on processLogical requests to all handlers, and not have a processLogical function in the Manager service
