SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 637

• Message text: Feld &1 enthält '-' (Bitte ändern)

Was verursacht dieses Problem?

According to the naming convention, the character '-' is not allowed in
an object name, but existing fields that contain this character are
accepted.
With the introduction of type definitions in the ABAP Dictionary, the
use of '-' in field names can result in inconsistencies. Example:
X and Y are structures:
X Field Type Y Field Type
B Y C DTEL3
B-C DTEL1 E DTEL4
D DTEL2
X-B-C is not unique. It could be either field B-C of structure X or
component C of structure B in X.
Structures with '-' in field names can only be addressed with LIKE in
ABAP programs, but not with TYPE. However, structures in which fields
contain structures as type cannot only be used with TYPE.

Wie behebe ich diesen Fehler?

Change the field names. The valid characters within a name are letters,
digits and underlining. Digits may not be in the first position.
