This read-create RowStatus object controls creation and deletion of entries in the CUG table, with the caveat that once cwaInterlockCode is set for a row it cannot be modified in place -- changing the interlock code requires deleting the row and creating a new one with the same CUG index. An admin who needs to reassign a different interlock code to an existing cwaCugIndex must destroy the current row via this object and then create a fresh one. This row-recreation requirement is a specific provisioning constraint an admin must plan around when reorganizing CUG memberships.
