The logic in the expression block is input 1+ input 2.
When input2 is empty due to deletion.The input1+input2 is not giving any output.

I presume you refer to Analytics Builder here.
Can you attach a simple exported model to show this, with instructions how to reproduce?

Can you share the model as suggested by Robert?

The Expression block will only activate if all connected inputs are available. If one of them is not available but you still want the block to activate, you need to provide the value through other means. The exact approach is specific for the intended behavior of the model. Potential options:

  • Missing Data block to react if no data is available
  • Constant Value block to provide a default value
