SET MARGIN x y.
Only in list display:
Print (see Printing in ABAP) with a margin of
x columns from the left-hand edge and (if specified) y
lines from the top of the page. x and y can be literals or variables.
The SET MARGIN statement always applies to the current
page. On a screen list, the statement has no effect - the list always has the same margin on the screen.
Important: If you create a screen list using SET MARGIN,
the system observes the margins when you print the list (System -> List -> Print), even though you cannot see them on the screen.
