Item Master Management
This guide explains how to use the item master management screen and master settings dashboard. It covers everything from registering and editing items to checking prices, component configurations, inventory, and related documents, as well as getting an overview of the overall settings.
What you can do on this screen
This screen is for managing information on items (all "things" handled within the company, such as products, parts, and raw materials). There are two types of custom screens.
- Item Master Management — A screen for registering, editing, and confirming one item at a time.
- Master Settings Dashboard — A screen that provides an overview of the settings for items, bill of materials (BOM), pricing, etc., across the entire company.
Both are positioned to complement the standard ERPNext item forms, allowing quick access to information frequently used in daily operations.
BOM (Bill of Materials) is a document that defines the list and quantities of parts and raw materials needed to manufacture a particular product.

- Safety Stock Setting: If set, a warning will be displayed in the order management sheet and requirements calculation when the inventory falls below a certain level.
- Lot Management: When turned ON, specifying a lot number is mandatory when receiving or shipping goods. Please turn this ON for items that require tracking.
- Early detection of missing settings: Regularly checking the alert panel on the master settings dashboard will help you find missing settings in the bill of materials or pricing early on.
