## Overview

The repository appears to define an SAP RAP sales-order application, with header and item entities, behavior handlers, and an exposed service. The README provides only the project name, and no source excerpts were supplied; relationships below are therefore tentative, based on the object names and file structure, rather than verified calls or data transfers.
