In DV, a custom script can be invoked in a Data Flow to perform some action(s). The general steps are:
1. Write some custom code (in Python, for example) and embed it in a pre-defined XML format
2. Upload the custom script via /dv > Create > Script
3. Create a Data Flow > Add a Data Set > Add the "Apply Custom Script" step and select the uploaded custom script > Specify Inputs / Parameters / Outputs for the script, as applicable
4. Add the "Save Data" step
5. Save and Run the Data Flow
In the "Apply Custom Script" step, if a column has been selected in error as a Parameter for the script, how can it be de-selected?
See the DV Unpivoting sample script at Oracle Analytics Examples Library
