Hello Devendra, 

I've tried to use your solution, but  I did what you told me and created the data action, however, I'm unable to set the Output type of the data action.

In this case I cant find a suitable output type.

Not sure if I'm doing some mistake. 

You have correctly set the data type, now you need to add an assign after the GetCheapestRoom action. In this assign, you fill Out1.

Hey Remco,

I did that, but now I'm not able to assign the Data Action to the Onclick of the button.

Hi Tiago,

You need to create a client action for button and on that client action you can call your server action.

To hold the server action results, you can create local variable as a same type of server action output parameter.

Thanks

Vinod

Hey Vinod, 

I have done that as we previously discussed, however the button has stoped working. 

The primal reason for this I believe, is that the output of the Server Action is not being used, as you can see on the pic (I might be wrong):

After that I assign the output values to the Local variable:

Bur for some reason this doesnt work. 

Thank you

Hi Tiago,

In your server action Getcheapestroom you are calling a SQL query but output of that is not assigned to out put of server action.

hey Devendra,

I reflected on your answer and into my understanding I'm not able to assign the output of the GetCheapestRoom Server Action to my screen var due to scope restrictions: 

But maybe I'm missing out something here. 

Thanks for your help.

Maybe its easier to share my OML.

Hi Tiago

Add this assignment and then check 

Also if doesnt work than please share BookingCore_TRU module as well . reference is missing

Best regards

Devendra

Also you are not using GetCheapestRoom server action and CheapestRoom structure in your screen you are using GetBookingByList aggregate See below image
