Short answer is that you cannot simply assign components of a composite type one-at-a-time, you have to build up the full final composite result in one expression and assign the result of the expression to the typed variable (p_my_type in this instance).​

​This works:

p_my_type := ROW(ROW(1, 'Teeeeeeeeeeest'), ROW('T', 10.56));

and execute:

​select * FROM fc_test(null)
