Answer 1

Data stored in these tables is different. If Oracle says that there's no record that satisfies the WHERE condition, why do you think that it lies? It is too stupid to do that.
Therefore, you need to handle the exception. There are several ways to do it. Here are some of them.
The first one is the most obvious - EXCEPTION handling section.
DECLARE
  default_value VARCHAR2(100);
BEGIN
  SELECT ISID INTO default_value
    FROM USER_TBL
    WHERE UPPER(ISID) = UPPER(:APP_USER);
  RETURN default_value;
EXCEPTION
  WHEN NO_DATA_FOUND THEN
    RETURN (null);  -- or whatever you find appropriate
END;Another one is to use aggregate function (MAX is a good choice) as it won't return NO-DATA-FOUND, but NULL:
DECLARE
  default_value VARCHAR2(100);
BEGIN
  SELECT MAX(ISID) INTO default_value
    FROM USER_TBL
    WHERE UPPER(ISID) = UPPER(:APP_USER);
  RETURN default_value;
END;
