@KavinrajT-150407 Because we are trying to set a target property via declare expression and also have it as part of the source expression. The declare expression target should have been a FullName property.

@KavinrajT-150407 Kindly check where you want to apply the declare expression, according to the screenshot it should be applied for FullName but you are trying to add it for Lastname.

Thanks

Hi @KavinrajT-150407

To create declare expression we have to decide target property and input properties.

Here your target and input both are same it will not work like that.

Create one more property “name” or “fullname” then create expression on that property like,

full name= first name+ Last name
