# DeleteSalesItem

## Permission Scope

salesItem

## Overview

DeleteSalesItem withdraws an item from selling by removing the sales module's record for it. The item itself is untouched and may still be purchased or stocked; it simply can no longer be put on a new sales order line.

## Business Rules

- The referenced item must already hold a selling record
- Sales orders that already reference the item are left untouched — they carry their own frozen line values and remain fulfillable and billable
- Withdrawal is reversible by adopting the item again, which starts a fresh selling record
