The documentation at http://www.tonymarston.net/php-mysql/virtual-private-databas e.html#implementation clearly indicates that you must use rdcaccout_id IN ADDITION to an existing key, so it is not possible to use it on its own.

It is possible to go to an UPDATE1 screen without starting at a LIST1 or LIST2 screen, but only if the current screen has the identity of the correct record in its WHERE string. Alternatively you can put code in the _cm_initialise() method to supply the relevant value manually, which means that the contents of the WHERE string as provided by the parent form becomes irrelevant.

If you are saying that the contents of the LIST1 screen should only show a single record, then you need to modify the ADD1 screen so that it will not allow additional records to be created. This can be done by hard-coding a single value for the primary key, thus avoiding the possibility of any user providing a different value.
