Use the Input tab to describe where a data resource ID (Data Catalog’s identification key) originates as input from within your transformation.
If your transformation only needs a specific data resource, type the ID into the Resource ID field. The Write Metadata step then adds new tags only to that specific data resource.
If the transformation is designed to work with multiple resource IDs, they can be supplied as input from a previous step in the transformation, for example, with the Read metadata step. Specify one of the following options.
| Resource ID option | Description |
|---|---|
| Accept resource ids from previous step | Select this option if the exact resource IDs are the incoming data from a previous step in the transformation. |
| Pass through fields from previous step | Select this option if the resource IDs are located in a specific field that is incoming from a previous step in the transformation. |
| Field in the input to use as resource id | If you select Pass through fields from previous step, enter the name of the field that contains the resource IDs. |
