In AX 2012 number sequence framework has been enanched with following things.
Scope
In AX 2012 number sequence , you must specify a scope. The scope can be Shared, Company, Legal entity, or Operating unit. Legal entity and company scopes can also be combined with Fiscal calendar period to create even more specific number sequences.
Segments
Number sequence formats consist of segments. Number sequences with a scope other than Shared can contain segments that correspond to the scope. For example, a number sequence with a scope of Legal entity can contain a legal entity segment. By including a scope segment in the number sequence format, you can identify the scope of a particular record by looking at its number.
In addition to segments that correspond to scopes, number sequence formats can contain Constant and Alphanumeric segments. A Constant segment contains a set of letters, numbers, or symbols that does not change. An Alphanumeric segment contains a set of letters or numbers that increment every time that a number is used.
Use a number sign (#) to represent incrementing numbers and an ampersand (&) to represent incrementing letters
