Can we call SP inside view?
No, but most-likely you can convert your stored procedure to a table-valued function. Then you can call the table-valued function in a view. The inline function will frequently provide more options to the optimizer than an multi-line function provides and will frequently optimize better.
What is difference between stored procedure and function?
The function must return a value but in Stored Procedure it is optional. Even a procedure can return zero or n values.
