Now that your Step Definition information is entered, it currently resides in a Pending state.
Pending State - While the Step Definition is in the Pending state, you can edit its attributes. Once the Step Definition is moved to the Active state you cannot edit its attributes, unless you move the Step Definition back to the Pending state. The Step Definition will not be used by the system until it is in the Active state.
Active State - To move the Step Definition to Active, click on the Step Definition State Icon 
You will now see that the Step Definition status has been updated to indicate it as Active. We will leave the part in the Active state.
You will also notice the extra icons available to toggle the step state. The step state can be toggled in the following order:
Pending 
Active 
Archived
Archived 
Active 
Pending
Archived State - This state is used to make a step inactive within the system.
