General Naming Conventions for Object Types

Object type ID

The ID must identify an object type uniquely. An ID has ten characters. It must begin with an uppercase letter. This can be followed by uppercase letters, digits and underscores. The ID is defined when an object type is created and entered into the field Object type.

Apart from the following restrictions, the ID is up to the user.

  • Object types created by a customer must begin with Y or Z
  • Object types provided by SAP must not begin with Y and Z
  • An object type that is a business object should have the same ID as the assigned data model

The IDs of business objects have the prefix BUS followed by a four-digit number ( BUSnnnn ).

  • The prefix IF is reserved for interfaces

You are recommended to use the name of the table in which the header attributes of the object type in question are stored as the ID. An object type appears with this ID as a transport object in the table TADIR : R3TR SOBJ <ObjectType>

Object name

The object name is specified when the object type is created. The object name has 20 characters and should be in English regardless of the user language. To make the object name easier to read, upper and lower cases should be used.

Object type name

The object type name is a short, language-dependent text with 20 characters, which can be used on screens or in lists to identify the object type.

The object type name is entered when the object type is created. It can be changed at any time in the basic data.

In the case of business objects, the object type name must be identical to the corresponding data model name.

Object type description

The object type description is an explanatory, language-dependent text with 80 characters, which can be used in lists of object types or for brief documentation.

The description is entered when the object type is created. It can be changed at any time in the basic data.

In the case of business objects, the description must be identical to the corresponding data model name.
