Problem on Obligatory Fields on Back Button

[Former Member]

Hi All,

I am having a problem with the obligatory fields when I click on the BACK button. It requires me to fill in entries for all required fields even if I want to click on the BACK button.

Thanks in advance.

Hi,

Give the function type for the button as 'E' and write your code in the MODULE <module_name> AT EXIT-COMMAND.

Thanks Nitwick. I thought I already have one set for my GUI-STATUS and that it is not working.

Hello Arlis,

The module with AT EXIT-COMMAND will do well to fix your issue;

what really happens is; when you validate certain fields using FIELD <field-name> MODULE <validate_fields>, and when you click 'BACK' or 'EXIT'; it will gonig to check the fields against the validate_fields module and then the error message which you have specified keeps popping up hampering you to get back to the desired screen.

All you can do is to; put sy-ucomm or ok_code like sy-ucomm, in the validate_fields module, so as to easily get back to the desired screen.

For instance;

MODULE validate_fields INPUT.
  IF NOT <field-name> IS INITIAL.
    SELECT * FROM trdir INTO TABLE t_table WHERE name = <field-name>.
    IF sy-subrc = 0.
      fl_flag = 'Y'.
    ELSE.
      fl_flag = 'N'.
      MESSAGE 'Invalid Program Name' TYPE 'E'.
    ENDIF.
  ELSEIF ok_code EQ 'BACK'.
    LEAVE TO SCREEN 0.
  ENDIF.
ENDMODULE.

I hope, it'll gonna help you fix the issue.

Kind Regards,
