Tableau CRM: Nodes with no data in Dataflow

 


First, it sounds weird when you said that your dataflow processed no data, but that could happen when you put a filter that clears off all data. What happened with the further nodes that create fields in the dataflow:

Augment with Right node has no data
  • Warning: The dataflow was completed, but the NodeName node didn't augment any columns. Either the node didn't find any matches, or a join key contains only null values.
  • Augment fields are created

Augment with Left node has no data
  • Warning: The dataflow was completed, but the NodeName node didn't augment any columns. Either the node didn't find any matches, or a join key contains only null values.
  • Augment fields are created

ComputeExpression
  • No error and no warning
  • ComputeExpression field is created

ComputeRelative with Expression Type = Source Field
  • No error and no warning
  • ComputeRelative field is created

ComputeRelative with Expression Type = SAQL
  • No error and no warning
  • ComputeRelative field is NOT created, because the field is not created, if you have any further transformation node that includes the new field, such as in slice, augment, etc., the dataflow will error. As per Salesforce, this is a defect, but no KI is created yet, the KI has been created, so feel free to "subscribe".
