Validation in selection screen

Former Member — Tue, 14 Apr 2009 16:33:11 GMT

Hi all,

I am doing validations in my selection screen. If i enter some garbage value, then at selection screen gets triggered and inside that i have checked the value entered in selection screen and am displaying error. My problem is, after the error if the user tries to enter the correct values the error keeps appearing or in other words it says " you have entered an incorrect entry". I am being forced to close the program and open it again to continue with the correct set of entries. Is there any wya by which i can do a refresh on the selection screen and continue with the corrrect entry?

Thnkz,

Hi,

Check the below code

PARAMETER : p_bukrs TYPE pa0001-bukrs.

AT SELECTION-SCREEN ON p_bukrs.
  IF NOT p_bukrs IS INITIAL.
    SELECT * FROM t001 WHERE bukrs EQ p_bukrs.
      IF sy-subrc NE 0.
        MESSAGE e016(pn) WITH 'ERROR MESSAGE'.
      ENDIF.
    ENDIF.

Thanks for your reply. But i am exactly using the statement as you all have mentioned. I am using at selection-screen on ( field name ). My problem is the incorrect entries are correctly identified and error message is being displayed, but if on the same screen i try entring correct value still the same error message is coming. I have to go back,execure the program again in order to continue with the correct data.

Hi,

If you are validating the select options then check whether initial values are getting populated in the initialization event and carried forward.

Can you paste your code here .
