你把这三个回退的button设成E就行了，
ABAP help里面写得很清楚。 当然你如果什么都不改，就只能通过在command 里面敲个/e,回车，一样能触发
Addition AT EXIT-COMMAND at the event PAI causes module mod to be called exactly if:
· The function used to trigger event PAI has function type "E"
· Into the command field of the standard toolbar, the user entered a character string starting with "E" and confirmed it using ENTER.
The dialog module is called before the automatic input checks defined in the system or in the ABAP Dictionary and independently of its position in the event block. The only screen field transported to the ABAP program is the OK field. If the function that triggered the PAI event does not fulfill any of the above prerequisites, the MODULE statement is NOT executed.
