I am facing an issue with the DwCompute() attribute which always returns a NULL value. Please help me out to get the computed value from that property instead of NULL value. 

 

For now I am doing this task manually for every property in the whole project by writing C# code as shown in the property below the red line.

 

I need the value from [DwCompute(" person_lastname +\" \" + person_firstname ")] attribute by returning proper value.

 

Highly waiting for your reply.

 

Thanks
