Normally, CICSPlex SM checks to see if it was responsible for placing the currently installed resource in the CICS® system. If so, CICSPlex SM does not install the resource, to avoid inadvertently changing attributes of an active resource.
If you specify YES in this field, CICSPlex SM bypasses this duplicate resource checking and installs the new resource unconditionally.
The resource definitions are associated "as is" with the specified scope; no assignment or override processing is performed.
