Merge 2 attributes?

Hi,
I have a BO with First name and Last name attributes.
How can I combine both attributes to display as First and Last Name combined in a column?

I have attached an image.
Thank you.

Add an Attribute called EstimatorDisplayName (add some length)

Then put a Rule on the BO

Estimator.DisplayName=Estimator.FirstName+' '+Estimator.LastName

Now use the DisplayName in the Query.

Alternatively, Use the new Dynamic Column feature in V8.1. with calculation of Estimator.FirstName+' '+Estimator.LastName

Thank you Mark 🙂
Regards,
Harry
