Hi All,
I have a requirement that, if BOM or Routing is made invalid (either BOM status made INACTIVE in Header or set DELETION flag for both BOM & ROUTING), in production version screen (Tcode: C223) the LIGHTS are to be displayed in RED 
as error indication when we click on check button
I've searched for Userexits/BAPI/Enhancements points but there are no such to suffice requirement.
Expecting your expert advice.
Rgds,
VKumar
