How To Fix DT277 - Struktur mit '-' in Feldnamen kann keinen strukturierten Typ enthalten

SAP Error Message - Details

• Message type: E = Error

• Message class: DT - Table activation (incl. indexes)

• Message number: 277

• Message text: Struktur mit '-' in Feldnamen kann keinen strukturierten Typ enthalten

Was verursacht dieses Problem?

According to the SAP naming convention, the character '-' is not
allowed within an object name. Existing fields that already contain
this character are accepted nevertheless.
With the introduction of type definitions in the ABAP Dictionary, the
use of '-' in field names can result in ambiguities. Example:
X and Y are structures:
X Fields Type Y Fields Type
B Y C DTEL3
B-C DTEL1 E DTEL4
D DTEL2
X-B-C is ambiguous. It can be either the field B-C of structure X or
component C of structure B of X.
Structures with '-' in field names can only be accessed in ABAP
programs with LIKE, but not with TYPE. Structures in which fields also
contain structures as type cannot be used only with TYPE.
You therefore cannot use a new field with structured type in this
structure.

Wie behebe ich diesen Fehler?

Do not use the field(s) with structured type or replace the fields
containing '-' with fields without this character.
