Was verursacht dieses Problem?

When maintaining matchcode sub-keys for a screen field, you failed to
specify either the field ID or the field name of the matchcode sub-key.

Systemantwort

To assign a matchcode sub-key to a screen field, you must specify both
the field ID and also a field name. Therefore the system rejects your
input.

Wie behebe ich diesen Fehler?

With matchcode selections, matchcode sub-keys allow you not only to
assign a selected value to the screen field where you make the
matchcode entry, but also to fill other screen fields as a result of
the selection.
When you define a matchcode object in the ABAP/4 Dictionary, you can
assign a field ID to a matchcode field. If a matchcode record is
selected, the value of the field is attached to the field ID (as with
GET/SET parameters).
If there is a matchcode sub-key for this field ID, the system places
the value attached to the field ID in the screen field whose field name
is specified as the relevant sub-key field name.
The functionality requires you to specify both a field ID and a sub-key
field name for a matchcode sub-key.
