New tab in PM order operation details (iw31/iw32)

In tcode IW32, in the operations tab screen >> there are buttons for internal ,external, enhancement etc.

When i click on a button, respective tab appears on operation detail screen.

I need an extra tab after the "Enhancement tab" .

Please let me know any exit or BADI that creates this tab.

IWO10018 creates tab at order header level , not at operation details level.
