Info object attributes (IO attributes) describe properties of instances of physical info objects. IO attributes can be, for example, language, format, or author. They can also be assigned to entities.

When defining the instance attributes of IO classes, you can use both the standard attributes that are predefined in the Knowledge Provider, and all other attributes defined in the various document areas. Of course, you can also create and use your own attributes.

To create an attribute, you need to reference a table field or structure field in the ABAP dictionary. When doing this, you specify the table name in the standard property TABLE_NAME and the referenced field name in the standard property FIELD_NAME. Provided that you have entered valid values, when you choose (Start data dictionary), you are taken directly to the referenced data element.
