deactivation request
A deactivation request corresponds to a modification of the property. After validating of the deactivation request by the experts, the value of the calculated status of the property changes to
replacement request
A replacement request corresponds to the creation of the property and the deactivation of the property it replaces. After validation of the replacement request by the experts, the replaced property
fragmentation request
A fragmentation request corresponds to the deactivation of the property and the creation of several properties. After validation of the fragmentation request by the experts, the fragmented property is deactivated.
