Just as we can customize the Dashboard, we can also customize the User Interface (UI) in SAP Business One. UI changes can be made by editing the form in the UI template. Some changes can now be made in the form settings window.
Customize the User Interface with Edit form UI
Open the form you want to change and choose Tools > Edit form UI.
Here you can add, delete, move, or hide fields or make fields inactive like below. See the differences between the two pictures.
Customize with the UI Configuration Template
You may also customize the UI by clicking Administration > Utilities > UI Configuration Template.
Here you may add forms and Assigned Users. Different UI templates can be created for different sets of end users. The template is assigned to users by name. These users will see the modified forms when they open the relevant window.
