               - The file is not located in
                  		  the workspace ("Type" attribute is incorrect).
                  		
               
- The "Name_Physical"
                  		  attribute value was not entered correctly.
                  		
               
- The file path is returned
                  		  incorrectly by another tool.
                  		
               
- The file path is correct but
                  		  the file simply does not exist.
