Dialog progg....(matching Field values from Table)

Question

Dear All,
                 I have one screen 0100.
At any stage, a field value entered in the screen field by user, should be matched from say EKBE table value with tolerance of  10-15%.
If it doesn't matches, Error message should display in  a dialog box.
Any suggestions, pls.
Thanks in Advance

Hi,
In PAI we can do this validation.
example :
In screen flow logic add CHAIN ..... ENDCHAIN and a module to validate the field
PROCESS AFTER INPUT.
  CHAIN.
    FIELD g_banfn.
    FIELD g_bnfpo MODULE validate_g_banfpo.
  ENDCHAIN.
And in Module validate according to your codition.
MODULE validate_g_banfpo INPUT.
* Validation.
Select ....
from ekbe
where some field = entered field on screen (e.g p_number)
  IF sy-subrc <> 0.
* if entered value is not present in table give an error message.
    MESSAGE e133.
  ENDIF.
ENDMODULE.                 " VALIDATE_G_BANFPO  INPUT
thanks.
