selectionColumnDesign=none has been set for the input-ready table &1

What causes this issue?

For the input-ready (readOnly = "false") table "&V1&", the
selectionColumnDesign property is set to "none". This combination of
both properties is not allowed. SelectionColumnDesign controls whether a
selection column can be displayed for the table or not. In tables, the
selection of a row takes place either through the selection column or by
left-clicking any field within the row. For table cell editors that
themselves react to the mouse click (for example, input fields, dropdown
boxes, and so on), there is no row selection. Therefore, to be able to
ensure a selection option for input-ready tables whose rows consist only
of such elements, selectionColumnDesign must not be set to "none".

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If the table has been make ready for input by mistake, set the property
readOnly to "true". Otherwise, set selectionColumnDesign to a different
value.
