Hello,

Error message will stop the excution of the program at the point it encounters the error message. Please try to give a information/warning message instead of error.

Hope it helps.

Hi,

An Error message stops further processing of the code. Read more about error messages thru F1 help.

Meanwhile try this...

Message e000 with 'Error' display like 'S'.

Try using it in PAI.

If you are not able to display data, you may use popup to display error.

In case of displaying multiple Error line FM like RSDC_SHOW_MESSAGES_POPUP can be useful.

FM is RSDC_SHOW_MESSAGES_POPUP.

DATA : gt_msg_disp TYPE TABLE OF bal_s_msg WITH HEADER LINE,
       gt_msg_user_act TYPE bal_s_excm.

CALL FUNCTION 'RSDC_SHOW_MESSAGES_POPUP'
      EXPORTING
        i_t_msg          = gt_msg_disp[]
        i_txt            = 'Message Log'
        i_one_msg_direct = ' '
      IMPORTING
        e_s_exit_command = gt_msg_user_act.

you can pass msgid, msgno, msgty, msgv1,msgv2, msgv3 and msgv4. Use msgid and msgno which can accept 4 message text i.e. & & & &

Error messages should not be used after start-of-selection .. Give I or S for the messages ..

Hi

I think it's because the error message stop processing: whene error condition is reached, error message is alerted to the user and processing is blocked. Try to substitute message with a popup, or try to change message error type.
