I'm working with Acumatica Moder UI 2025R2

Hi @vannakheng

Here is the physical file location for local development in folder FrontendSources:

To build the sources during the UI development, you run the following command in the FrontendSources folder:

npm run build-dev

Examples for specific screens-> 

Standard Acumatica screen: SO301000 and custom screen: IGXX5099:

FrontendSources\screen folder:

npm run build-dev --- --env customFolder=development screenIds=SO301000
npm run build-dev --- --env customFolder=development screenIds=IGXX5099

Modern UI Files section:

Hi ​@vannakheng 

You use the development folder—located in the FrontendSources\screen\src\ folder of your instance—to create new forms or to customize existing forms for the Modern UI. If the development folder is not found, you need to create it manually.

For details, see Including Files in the Customization Project

thanks, lets me try

Is it working with all tenant ?

Hi @vannakheng

When publishing a package with Modern UI files, Acumatica automatically places them in the following path by tenantName:

FrontendSources\screen\src\customizationScreens\{tenantName}\screens\{Module}\{ScreenID}

Please refer to the link above. It contains all the necessary details and steps specifically for the Modern UI implementation.
