How To Fix 28069 - Partial key expression = expected

SAP Error Message - Details

• Message class: 28 - Configuration

• Message number: 069

• Message text: Partial key expression = expected

What causes this issue?

The syntax check found an error in your entry for an object key.
To refer to an object, you enter the object identifier, class type, and
object key:
(Material)(300)(NR='M4711')
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 identifier for materials.
In the <LS>Define object keys</> step, the object keys for an object
type are displayed. The fields of the object key also have a field
identifier used to refer to them in object dependencies. The object key
for materials is the material number. The material number is accessed
via the object ID 'NR'.
The object key can consist of several fields, as is the case for
documents, for example:
(Document)(017)(TYPE=DRW, VERSION=00, PART=000, NR='bmw-ca31')

System Response

The cursor marks the incorrect object entry.
