The Inputs card is a card in the SWARM Ops Dashboard that allows users to view and potentially edit data that has been hydrated into the application from the Data Preparation card.
If you have multiple datasets for your solution, then there will be a dropdown at the top of the card that allows you select which dataset you'd like to review and potentially edit. Sometimes data may be editable in the Inputs card - it is completely dependent on your team's requirements and restrictions on being able to change your source data before generating a solution.
Hint
It's a good best practice to briefly review each dataset in the Inputs card after completing the Data Preparation card to ensure that each dataset looks correct, that the data has been brought correctly into the application, and that there aren't any significant missing pieces of data.
