====== TriggerTable ========
 
**Problem:** Adding Task FailureInBackendObjectTransmitter in node /System: TriggerTable of _dataSet is null

**Cause:** The  [[en:transformation:mappings:objektdefinition:attribute|MapTrigger]] is missing. Attribute in the root element of the data object.

**Solution:** Define the [[en:transformation:mappings:objektdefinition:attribute|MapTrigger]] attribute at the root element of the data object, and recompile object class.
