Hello Ana,
Looking at shared image it looks that is missing the Posting Groups combination needed for "VPORTES"..
In fact your Item charge has the code as "V-PORTES-NAC" and you probably just made the Posting Groups for NAC Business.
I would suggest to take a look at your Product Posting Group "VPORTES" setup and add the combination for Business Group UE too.
Hope this information help you to move forward.
