Since the number of loop blocks in variable step loops can change the number of loop blocks at any moment is placed by the system in system field SY-LOOPC and the current step loop pass number is placed in system field SY-STEPL. ENDLOOP to program step loops in a screen in both PBO and PAI. In a fixed size loop the number of loop blocks shown in the screen is fixed,while in case of variable size step loop the number of blocks will change dynamically according to the size of the screen.There could be only one variable step loop per screen and unlimited fixed size step loops per screen.Ī step loop can extend more than one line on the screen(see Table Control).A vertical scroll bar is automatically created to show step loops on he screen.
