# Delete Header Purchase Change Order

> # PO Change Order — Delete

## Overview

Deletes a change order, identified by its unique identifier, together with all of its summary  
lines.

## Notes

- Summary lines are removed **first**, then the header — the database does not cascade the  
    header delete, so this ordering is required to preserve referential integrity.
    
- The whole delete runs in a single transaction and is rolled back entirely if any step fails.
    

## UI Navigation

Asset Management → Purchase Order → Change Orders → Enter Change Order

## Finders

Not applicable — targets a single record by `POCOH_V_UUID`.
