standard text in transaction...

Hi i'm new in sdn, and i must tell you that my English is not so good by this days. Im learning little more every day.

My problem is that i need to change some standard text in transaction FCH5. i wonder if i can change for example a text in a field saying "section" to "date of collection", because i need to reuse a field to put some extra data, that is essential for my funtionality...

Again, sorry for my written English,

i'll be waiting for your answers....

thankyou very much to all...

Andriu.
