By design, SAP script is a word processing tool which

displays data on the form with the help of text elements

where the logic of those is written in the print program and

Forms were designed to be driven from print program, hence

are often termed as client dependent. Smart forms are client

independent. Bcoz it doesn’t use any text elements. It will

be executed through a function module. When a print program

calls a Smart Form, the form itself takes over to produce

output, without any further direction from print program.
