Setting Default value in Data Factory Copy Activity in mappings

Just wondering how can we set a Default value in Data Factory Copy Activity in mappings.

Trying to do following

Azure Data Factory Source Dataset value from Parameter

But if that's not possible, can I set a default value through parameter while defining mappings?

To achieve your requirement, you could define a pipeline parameter with "Object" type and give it a default value, eg. name it as "columnMapping" and set the default value as: 

                {
                    "type": "Object",
                    "defaultValue": {
                        "type": "TabularTranslator",
                        "columnMappings": {
                            "Prop_0": "Prop_0",
                            "Prop_1": "Prop_1",
                            "Prop_2": "Prop_2"
                        }
                    }
                }

then assign the parameter to the copy activity column mapping:

          "translator": {
                            "value": "@pipeline().parameters.columnMappings",
                            "type": "Expression"
                        }
