On the Data Analysis tab page, you can change the parameters of the selected PAL function.
To use the functions on this tab page, you must have selected a PAL function for data analysis.
You can find the documentation for the PAL functions (and your parameters) in the SAP HANAPredictive Analysis Library (PAL).
In the data transfer process, you can also view and edit these input fields under Extraktion. These entry fields are available for all PAL functions in the query monitor, though only if the source data is accessed directly, i.e. if the result has not been saved.
