How To Fix NP637 - Feld & enthält '-' (Bitte ändern)

SAP Error Message - Details

• Message type: E = Error

• Message class: NP - New checks in the activating program

• Message number: 637

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

&USE&
The character '-' is not allowed within an object name in the SAP
naming convention. Existing fields that contain this character,
however, are accepted.
With the introduction of type definitions in the ABAP Dictionary, using
'-' in field names can result in ambiguity. 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 field B-C of structure X, or
component C of structure B of X.
Structures with '-' in field names can only be addressed with LIKE, but
not with TYPE, in ABAP programs. Structures in which fields contain
structures as type, on the other hand, can 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 appear in the first position.
