This image shows the Orchestration design page, specifically the Service Request step and orchestration inputs sections.
The Service Request step is Get_AddressBooks. Below the name is the status of the user defined object (which in this case is "personal" for all three steps) and the object name/ID of the user defined object.

Below the steps grid is another grid for working with orchestration inputs, which is divided into three separate expandable grids: Orchestration Inputs, Values from Steps, and System Values. 
The Values from Steps section is exapnded to sho the following single input:
Input = Get_AddressBooks.output; Value Type = String 
The row for this input contains "Get AddressBooks", uneditable text at the beginning of the row to indicate that this input is an array (contains a data set to retrieve multiple values).
