Hi Marco.
There is chance to do what you want using implicit enhancements, but you must use it carefully.
In the include LRHOMDETAILMANAGERF01 there is a subroutine named INIT_PERIODS, this subroutine is called from a PBO module of Dynpro 0300, so as you can not modify directly this standard include you must use implicit enhancements.
After you have created the enhancement you will be able to add some code at the end of subroutine..  you can make use of field "act_info-tabtype" to identify the active tab, after that you should perform a loop at screen and change the input field to 0.
the source code looks like this:
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""$"$\SE:(1) Forma INIT_PERIODS, Final                                                                                A
$$-Start: (1)----
$$
ENHANCEMENT 1  ZHCMOM001.    "active version
  if act_info-tabtype = 'IT9001'.
    loop at screen.
      if screen-name = 'DISPLAY_PERIOD-BEGDA'.
        screen-input = 0. "Inactivate
        modify screen.
      endif.
    endloop.
  else.
    loop at screen.
      if screen-name = 'DISPLAY_PERIOD-BEGDA'.
        screen-input = 1. "Activate
        modify screen.
      endif.
    endloop.
  endif.
ENDENHANCEMENT.
$$-End:   (1)----
$$
Don't forget activate the enhancement.
Let me know if it works.
