How to fix this error?

An object is accessed by entering the object identifier, the class
type, and the object key:
(Material)(300)(NR='M4711')
The object key can consist of several parts, as is the case with
documents, for example:
(Document)(017)(TYPE=DRW, VERSION=00, PART=000, NR='bmw-ca31')
The object identifier and object key are defined in the IMG for
<ZH>Classification</>.
In the <LS>Define object types</> step, an object identifier is defined
for each object type. This identifies the object type in dependency
maintenance functions. 'Material' is the object ID for materials.
'Document' is the object ID for documents.
In the <LS>Define object keys</> step, you see the object key for an
object type. The fields of the object key have a special field ID,
which is used to refer to the fields in object dependencies. The object
key for materials is the material number. The material number has the
object ID 'NR'. For documents, the key fields have the object IDs
'TYPE', 'VERSION', 'PART', and 'NR'.
The names of the key fields can be no longer than 10 characters.
Correct the names you entered accordingly.
