Position the cursor on a valid field name field

What causes this issue?

When editing the attributes of a table control, you chose the
<LS>Attributes</> function.
However, the cursor is not on a field for which field attributes can be
displayed or edited.

System Response

The system can only execute the function if the cursor is on the field
name field for the title or the line selection column of the table
controls, and the title and/or line selection field already exist(s) or
can be created.
If you are in change mode, the title field and/or the line selection
field can only be created if the attribute "With title" and/or "With
selection column" is (are) set und the appropriate field name field is
consequently ready for input.

How to fix this error?

Place the cursor on a valid field or set the attribute accordingly,
choose <LS>Refresh</> and then repeat <LS>Attributes</>.
