HBO0069I The value specified for case n is of incorrect type.

Explanation

In a case expression, the expression that follows the THEN keyword number n is not of a type allowed for the result of a case expression (for example, a labeled duration or a value of true or false).

If the case expression contains nested case expressions, the keywords THEN and ELSE of these subexpressions are not included in the n. If the n is 1 greater than the number of THEN keywords in the expression, it refers to the expression after the ELSE keyword.
