You can also add elements without first selecting fields from the Dict./program fields dialog. You may prefer this if you want to add all elements to the screen before declaring corresponding fields in your program or defining them in the ABAP Dictionary. SAP does not recommend this method, however, since you lose the advantage of the centralized Dictionary definitions.

When you add elements without corresponding fields, you must also provide a field name explicitly (the Field name field in the fullscreen editor). Enter a field name (up to 40 characters long). The name can contain only alphabetic and the special characters # (pound sign), / (forward slash), - (dash), _ (underscore),$ (dollar sign).

If you enter a field name with a - (dash), the system checks to see if the ABAP Dictionary contains the field. If it does, a dialog box appears, in which you can decide whether your field should refer to the ABAP Dictionary field.
