    Hi BK, The getProperty function returns a string, not an Item. You should update your code as shown below to declare the itmid variable to be a string. 
    Innovator inn=this.getInnovator();
string itmid=this.getProperty("item_number"); // <-- getProperty returns a string
//return this.getInnovator().newError("hello");
if(itmid.Length == 20)
{
return this.getInnovator().newError("Invalid Value!");
}
return this; // <-- Server-side methods always need to return an Item
