Add UPC Field to General Product Information

App/Module: D-Tools SI Desktop

Problem/Current Behavior: The "General" information page for products and labor items in the D-Tools catalog lacks a dedicated field for the Universal Product Code (UPC). This essential identifier is often needed for inventory management, purchasing, and integration with other systems.

Proposed Solution: Add a standard text field labeled "UPC" to the General tab for both Products and Labor Items.

Benefit: This allows for easier product tracking, streamlines ordering processes, and enables seamless integration with barcode scanning systems for inventory and logistics management.
