General Rules
All names must be in U.S. English.
The default rule is to use logical and descriptive names if no other specialized rules apply.
Identifier names have a limit of 40 characters.
Names in the Application Object Tree (AOT) and in X++ code must correspond to the names in the U.S. English user interface.
Names must be spelled correctly.
Names must be used consistently.
Each path in the AOT must be unique; nodes must not have identical names.
All texts that appear in the user interface must be defined by using a label. (This rule applies only if you want your solution certified as an international solution.)
Do not begin a name with "aaa", or "CopyOf". Do not begin a name with "DEL_" unless it is a table, extended data type or enum, and it is needed for data upgrade purposes. Names that use these prefixes cause a best practices error when you check the objects into the version control system.
