I have made Dialog Program there is one Table control in it

i have put some validation in Loop at chain in PAI if user enters wrong value system displays error message. this is working fine

my requirement is that if user enters wrong value then the system shud also allow to go back or EXIT the application.

how to avoid the validation if user press BACK or EXIT button.

if u want to exit before any validation

in the PAI,add the module exit at exit-commandat the first line in Process after input and write the logic for exit

In this screen,U are using a back button i.e., GUI status for BACK,and this is of EXIT type(E).

and U have made a field on the screen as mandatory (using attributes in screen painter).

Now,when u try to go out of this screen using the back button.U will get an error message(Fill in all required fields)

Now,our module ON EXIT COMMAND comes into play.

If this module is prsent in our code.It overtakes control from the mandatory filed and allows U to move out of screen using the BACK button(coz it is of EXIT type)

Assign the Function type of the push buttons as 'E' then the system bypasses the validations and calls a special module in the screen flow logic, check the link and analyse the example program provided.

CASE OK_CODE.

WHEN 'BACK' OR '%EX' OR 'RW'.

LEAVE TO SCREEN 0.

ENDCASE.

endmodule. " USER_COMMAND_1000 INPUT

Hi,

After user enters the value and the presses some button the system go to PAI module. In PAI module check whether user has pressed any button on screen.

Pleace your button press logic before the validation.

If BACK or EXIT button is pressed you cal use CALL SCREEN XXXX.

You can call same or any other screen.
