Hi
you can use the second option i mentioned in my solution , this option does not need you to extend the vendor to another company code:
use F-53 and fill data as usual in CoCd 1009 :
Just before you write the vendor code that belong to another company code only check the box other account , this box will open a screen you will be able to choose vendor /vendor's from another CoCd to pay.
