New Naming Conventions
In ABAP Objects, the following statements cause an error message:
DATA: field-name TYPE ...,
1name TYPE ...
Correct syntax:
DATA: field_name TYPE ...,
name1 TYPE ...
Cause:
You cannot use special characters in names, because they often have a particular meaning in the system. The new naming conventions correspond to those for other programming languages.
