Copying a record

I've experienced that one of the tasks often used when manipulating data is record copying.
For various reasons, an existing record needs to be modified and saved as a new one. The
most obvious example could be when a user requires a function that allows him or her to
quickly duplicate records on any of the existing forms.
There are several ways of copying one record into another in X++. In this recipe, we will explain
the usage of table data() method, global buf2buf() function, and their differences. As an
example, we will copy one of the existing customer records into a new one. Normally, copying
a customer involves more data around the customer like customer contacts, bank accounts,
printing settings, and similar, but for demonstration purposes, we will assume that our goal is
only to copy the customer record itself without worrying about related data.
