Lock mode for table & meaningless since no base table exists

What causes this issue?

When defining the lock object, a table was assigned a
<DS:TX.DDDOK_ENQU_MODE>lock mode</> which is not a base table of the
lock object. This is meaningless.

System Response

The action was cancelled.

How to fix this error?

If you really want to lock the relevant table with the lock object,
extend the list of base tables of the object accordingly. Otherwise
delete the specification of the lock mode to the corresponding table.
