using noinput on inputfields.
The noinput command operates slightly differently depending on the target screen element. We will demonstrate how to use noinput on an inputfield. To demonstrate how noinput works with inputfields, please do the following:
Go to the VA01 script file and enter the following code:
noinput("F[Sales Organization]");
Save your changes and refresh the screen.
The VA01 screen now appears as shown below:

This process works on checkboxes as well. the only difference is the element designation. for checkboxes, you would write the following syntax:
noinput("C[checkbox_label]");
