translate transaction+change title in sap trans.

Hi everyone,

we have a client that dont want to see the words: "business entity" - instead he want to see the word: "site"!!!!(RE module)

(i know that it repair,,,,it doesnt )

so, i changed most of it - but i have a few problems that i dont know how to translate:

1. trans. REISBE there is a title business entity and when i press F8 there is also a title.

2. RE80->Information system->Master data->business entity - how do i change the name in the menu?

3. Sap menu->accounting->flexible real estate management->master data->precess business entity-> change the title business entity.

any help will be apreciated,

thanks in advamced,

Michal.
