Loading re-usable combo box from Service Method

Hello all,

Still new & learning app studio. I am trying to create a re-usable combo box using service Ice.BO.SysPrinterSvc along with the GetRows method. My goal here is to have a drop down list of printers as selectable options.

I am struggling with correctly pointing the combo box fields along with initializing the data view using the rest-erp widget.

    Epi Binding to SysPrinter view & dataset

  1. Initialize dataview SysPrinter using Rest-Erp widget:

Rest Services:

Method Parameters:

I see the get rows automatically pulls method parameters. Is it best to set a static value field or should these be set to columns of the dataview?

Response Parameter:

These are all the configurations I have for this event. Like I mentioned, relatively new to application studio / Epicor all together so any pointers are greatly appreciated!
