 4. The mapping `SyncMapping` needs to be configured foreach entity as it is the list used as reference for the lookup.
 5. The `SyncState` should be created for each mapping. This can be done with this query after creating all the `SyncMapping`:
     ```
-    `INSERT INTO nti_sync_mapping(mapping_id, timestamp) SELECT id, 0  FROM sync_nti_mapping;`
+    `INSERT INTO nti_sync_state(mapping_id, timestamp) SELECT id, 0  FROM sync_nti_mapping;`
 6. If the entity is going to be synched FROM the client, then a service must be defined in the `SyncMapping` database entry. Also, this method needs to implement the interface `SyncServiceInterface`.
