SmartPlant Foundation generates a Resurrection instruction when it notices that the Intergraph Smart Instrumentation database is not synchronized with current values it received from another application's published data.
Since SmartPlant Foundation identifies that the Intergraph Smart Instrumentation database needs to be synchronized, it generates Resurrection instructions in the Tombstone document.
The SmartPlant Adapter, which receives these instructions during a retrieve, goes over all available tasks in the To Do List. It removes deleted instructions which still exist there and have not yet been processed and which are not synchronized with the current SmartPlant Foundation database values (meaning that they are no longer needed).
The handling of the Resurrection instructions is done in the INtoolsEFAdapter module via the function RetrieveTombstones().
