Transaction CKM3N

Hi All,

I just want to make Enhancement on Transaction CKM3N.

The Enhancement will cover Select-Options on Materialnumber, Materialart, Period/Year. Standard is now

only one Value into these Fields are giveable.

How can we better make Changes on this Transaction without any Restrictions for the Future due to a ReleaseUpdate. Is copying of this Transaction to a Z-Transaction the better Way or ýs There another Ways of doing it?

Thank you for your Replies.
