ABAP_DDIC - Naming Rules for Data Types
The name of a DDIC data type must stick to the following rules:
It can have a maximum of 30 characters.
It can consist of letters, digits, and underscores.
It must start with a letter.
It can be introduced using a namespace prefix (/.../) of a prefix namespace
It is in the same namespace of all global types of an AS ABAP.
It must not be the name of a built-in data type in ABAP.
All DDIC data types, alongside DDIC database tables and DDIC views, are located in the same namespace which includes all global types of an AS ABAP. DDIC domains, on the other hand, are in a separate namespace, and can therefore have the same name as, for example, a data element.



Latest notes:

NON_V5_HINTS
DDIC types are stored in uppercase letters, as all repository objects of the ABAP repository. Names that are entered in lowercase or mixed case letters in the tools for dictionary objects are converted to upper case internally.
In addition to the above rules, there are special
naming rules for DDIC structures
naming rules for DDIC database tables
naming rules for DDIC views
