Select the target object for the Target transformation on the Target tab of the Properties panel.
The properties that you configure for the target object vary based on the connection type and the mapping type. Your organization's licenses can also determine the target properties that appear when the Target transformation is part of a mapplet.
The following image shows the Target tab for a flat file target:

2Select the target object from the mapping inventory.
You can select a target object in the following ways:
Select the connection and target object.
In the Details area, select the target connection, target type, and target object. You can create a new connection. For flat file and relational targets, you can also create the target object at run time. For mappings in SQL ELT mode, you configure the target connection in the mapping properties instead of in the Target transformation.
If you use an existing target object, select the target from a list of target objects and link the target to the upstream transformation. If the target table changes, you must update the Target transformation to match it. If the physical target and the Target transformation do not match, the mapping fails.
If you use an existing target object for a flat file target, the existing target is overwritten when you run the mapping task.
Select the target object from the mapping inventory.
If your organization administrator has configured Enterprise Data Catalog integration properties, and you have added objects to the mapping from the Data Catalog page, you can select the target object from the Inventory panel. If your organization administrator has not configured Enterprise Data Catalog integration properties or you have not performed data catalog discovery, the Inventory panel is empty. For more information about data catalog discovery, see Mappings.
The Inventory panel isn't available in mappings in SQL ELT mode.
Use a parameter.
You can use input parameters to define the target connection and target object when you run the mapping task. For more information about parameters, see Mappings.
You must also define the target operation. The available target operations vary based on the connection type.
Target file creation on advanced clusters
When you create a mapping that runs on an advanced cluster and contains a complex file target, the Target transformation creates a folder with the file name you enter in the File Name property in the Advanced area. It does not create a single file. This is necessary because the output may be divided into a series of files.
The folder name might also be appended with a unique identifier. You do not need to know the identifier, because the mapping recognizes the file name and all the contents within the folder.
The part files within the folder are named: part-<unique identifier>.<format>, where the suffix can be csv, txt, avro, parquet, json, orc.
