error-handling in form routines to be called from maintenance view

[Former Member]

hello,

i have created a table maint. dialog. Under 'enviroment->modification->events' you can create form-routines for your own coding.

I have the maint.event '01 - Before saving the data in the database'. Here i do some checks if entered values in some fields are okay or not etc.....

When the users enters 'wrong' data i do a "message e000 with 'text' " So i got a error-message and the user is not able to save the data before changing it.

BUT: i get the right error-message in the status-line, but i got an EMPTY screen, all the fields disapear. I have to go back with enter or the red cancel button. But then i 'fall back' to the selection screen of the maint. view. Thats not very user-friendly.

Any ideas ?

Hi

Why don't use the event 05 for new entry?

hi max,

i ALSO use event 05. but event 05 is for creating a NEW entry in the database !! i make my checks there, and there it works right.

but i can't use the event 05 for changing data, right ? so i have to use the event 01.

Hi martin,

1. use different message types.

2. form mysave.

break-point.

if ZAM_TBL01-MATNR is initial.

message 'error ' type 'E'.

else.

message 'OK' type 'S'.

endif.

endform.

Amit,

i can see no difference between my error-handling and yours ?? I don't understand your posting

what do you mean by 'use different message types' ? i only can use 'E', as i DONT'T want the data to be saved !

Also you use type 'E'in your mysave-coding. So what do you want to explain to me ?

Hi Martin

You can try to use the event 21 to fill the hide fields, infact I saw the SM30 triggers that event although it doesn't use hide fields.

hi,

think you have place your module not correct:

try that: (without event)

PROCESS AFTER INPUT.
...
  LOOP AT EXTRACT.
...
    FIELD VIM_MARKED MODULE LISTE_MARK_CHECKBOX.
    CHAIN.
      FIELD Y789.
      FIELD Y012.
      ...
      MODULE LISTE_UPDATE_LISTE.
    ENDCHAIN.
*begin of insertation
    CHAIN.
      FIELD Y123.
      FIELD Y456.
      module check_field  ON CHAIN-input.
    ENDCHAIN.
*end of insertation
  ENDLOOP.
...
