If you use the STOP statement within an event block, the
system stops processing the block immediately. The ABAP
runtime environment triggers the next event.
Before and during selection screen processing, the next
event in the prescribed sequence is always called. From the
AT SELECTION-SCREEN event onwards, the system always jumps
from a STOP statement directly to the END-OF-SELECTION
statement. Once the corresponding event block has been
processed, the system displays the list.
EXIT
If you use the EXIT statement within an event block but not
in a loop, the system stops processing the block immediately.
Before and during selection screen processing, the next
event in the prescribed sequence is always called. From the
START-OF-SELECTION event onwards, the system starts the list
processor directly when the EXIT statement occurs, and
displays the list.
If the EXIT statement occurs in a loop using DO, WHILE, or
LOOP, it is the loop that terminates, not the processing block.
CHECK : if the statement fails then skips the current loop
pass. But it doesnot exit the loop.
CONTINUE : skips the current loop pass. But it doesnot exit
the loop.
