Hi Sudha Kumari,

Tried to control actions with input?

Thankyou,
Murilo Antonio.

Hello

Would you like to display the error in a pop-up or feedback message will work for you,

So you can check the result on the after-fetch event of the aggregate from which you are fetching the mission details, So if the mission exists you will use the end node on a true branch but if the mission doesn't exist you can show the error message and redirect the user back to the list screen.

• Create a new output parameter as Is empty default value false , as you are not returning data in a list or a structure you have created all output parameters( suggest to create a structure with all the output so that it will be combined in a single Output(structure)
• Now as you are already checked the empty property by the condition
  GetMissionDetailsByMissionId.OutMissionDetails.Length > 0
  
• Now as we have assigned IsEmpty to true now we can check the condition whether it has returned some data or it is empty 
• Now coming back to the after-fetch event of a data action as we have created an action on it.
• Now on the action flow, we can check the IsEmpty property.
• 

I hope this will help you
