abort bsp-application

Hello !

i have one question:

......

insert xy from w_xy.

insert ab from w_ab.

if sy-subrc <> 0.

message a001(xy).

endif.

if i have this code in a normal abap-Program it works fine and if i get the abort-message from the second insert, also the first is not done.

but if i have it in a on-input-processing in my bsp-application, i do get the errormessage (thats fine for me), but the first insert is done.

does anybody no why?

how can i abort my bsp-application immediately (like with the message a... in normal abap).

thanks very much for your help
