u might have used

if sy-subrc ne 0

error message

before giving error message write clear <field name>.

and to make that field editable incase it gets disabled, in the PAI of that screen

write

field <field name > module <module name > on request

inside this module write ur validation code

Are you moving the 0 value to the screen field before issuing the error message?

hi,

u are clearing the screen field in the PAI module of the program, but this cleared field value is passed to the screen only after the PBO. As error message is executed immediately after the CLEAR statement program execution stops there itself without executing the PBO module. So old value is displayed on the screen.

 CHAIN.
    FIELD v_new_qty.
    MODULE f_message.
  ENDCHAIN.

CLEAR : v_syucomm.

  v_syucomm = sy-ucomm.
  v_qty = v_new_qty.
  IF v_syucomm EQ 'ENTER'.
    IF v_qty < 0.
      PERFORM f_clear.
      MESSAGE e001(z2c_gdmvt).
    ELSEIF v_qty > v_vmng.
      PERFORM f_clear.
      MESSAGE e002(z2c_gdmvt).
    ENDIF.
  ENDIF.

pls check the code for ur reference..
