About App Studio

App Studio (U4AS) is a U4 low-code/no-code app editor that enables U4 developers, customers, consultants, and partners to extend ERPx by creating Business screen apps and/or Standalone apps. U4AS is the app repository and editor of Extension Kit's portal.

U4AS produces reusable and responsive applications that are secured by Unit4 Identity Services that work with ERPx.

App Studio currently uses components from two design systems:

• The Unit4 NextGen design system (U4 components). Apps created previous to the 251.2.0 release use this design system.
• The Unit4 Ripple design system. New apps created after the 251.2.0 release will use this design system.

Both design systems can coexist in App Studio:

• If you have created apps previously with U4 components, you can edit, publish, unpublish and delete them, but you cannot duplicate or create new apps with U4 components.
• New apps will be created with Ripple components.
• You cannot import U4 components apps metadata to Ripple apps.
