SAP Error Message - Details

• Message type: E = Error

• Message class: SWDP_WB_TOOL - Web Dynpro: Messages for Workbench Tools

• Message number: 427

• Message text: Do not specify ' ' as the property "rowSelectable" of the element "&1"

What causes this issue?

The property "rowSelectable" of the element "&v1&" should either have
the value 'X' or it should be bound to the context.
This property allows you, through context binding, to make certain
targeted table lines selectable or non-selectable. For example, in Web
Dynpro ABAP, ALV totals lines for (interim) results should not be
selectable because they do not correspond to any data.

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?

Change the value of the property accordingly.
If you wish to ensure that the table cannot be selected or is to
function merely as a display table, set the property "selectionMode" to
the value "none" instead.
