Transaction goes to display mode after an error message / POPUP - Urgent

Question

Hi All,
    We have a requirement that, in the Service order transaction IW31/ IW32 in the components tab ,  based on the material numbers entered by the user we need to call a Popup and inform user to fill in the correct value for special stock indicator.
   I tried using the BADI Workorder_update , but within that I could not call a pop up or a message.  I tried using the exit  EXIT_SAPLCOMK_014 where
   in I collect the incorrect components and call a POP UP with all of them. But once I call the POP UP the IW31/IW32 screen in the background goes
   to display mode and then we are not able to change the value as per information from the POP UP.  This is the same problem that we faced with the
   BADI.
  Please let me know if this could be handled in any other way.
Regards,
