Output Message ME9F

Dear Expert,

Can I add an additional field ( for ex: vendor number) in the output message ME9F? So that when I print it out I can see not only the vendor name but also the vendor number ( it is better if I can allocate the vendor number just above the vendor name)

If can, How to do the adding of the field? and how to allocate the position of the field?

Thanks

Pauline
