The Delete from Model stage deletes entities and relationships from a Context Graph model.
A dataflow that uses a Delete from Model stage requires an input stage that contains data from or queries the same model whose elements you are deleting. It also has two optional output ports: one contains data for the deleted entities and relationships and the other contains data for the records that were not deleted.
To configure a Delete from Model stage, you need to select the model you want to modify and then complete the Delete from Model Options settings.
