Was verursacht dieses Problem?

The creation of an LIS inbound interface is dependent on a
communication structure. This communication structure needs to satisfy
particular requirements. It must contain a field of type DATS, for
example.
The IDoc consists of the following structures:

Das System gibt eine Fehlermeldung aus und erlaubt Ihnen nicht, mit dieser Transaktion fortzufahren, bis der Fehler behoben ist.

<ZH>Inbound structure</>
Please observe the naming convention E1, ...!
The inbound structure is the structure to which the data flows. It only
consists of fields of the type CHARACTER.
<ZH>Check structure ALE</>
Please observe naming convention E2, ...!
You can ignore the check structure in this case.
<ZH>Documentation structure / outbound structure</>
Please observe naming convention E3, ...!
The outbound structure is the structure to which the entered data is
transferred. This is where conversion takes place (number fields of
the type CHARACTER from the inbound structure become number fields of
the type NUMERIC, for example).
The outbound structure is then transferred to the corresponding
application for further processing. This structure then corresponds to
the SAP definition of a communication structure.
