- Naming Rules for Data Types

The name of a data type defined in the ABAP Dictionary must meet the following rules:

• It can have a maximum of 30 characters.

• I 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 types created in the ABAP Dictionary, including DDIC database tables and DDIC views, are located in the namespace of all global types of an AS ABAP. DDIC domains, on the other hand, are in a separate namespace, which enables them to have the same name as, for example, a data element.

Notes

• As all repository objects of the ABAP repository, DDIC types are stored in uppercase letters. 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
