I got some error. BIP2436E, Invalid index assignment to '2'.

Array elements are positional within message trees. You can't reference element[2] unless element[1] currently exists. When you propagate OutputRoot, if you delete its elements, you'll want to reset its index counter(s) too. For example:
Code:
DECLARE x INTEGER;  -- Environment.IXSB055PX[x]
DECLARE Count INTEGER CARDINALITY(Environment.IXSB055PX[]);

DECLARE y INTEGER;  -- Environment.IXSB066PX[y]
DECLARE Dtl INTEGER CARDINALITY(Environment.IXSB066PX[]);

DECLARE k INTEGER;  -- OutputRoot.XMLNS.Envelope.PO.PODetail.Item[k]

SET x = 1;
WHILE (x <= Count) DO
    -- OutputRoot is empty
    CALL CopyMessageHeaders();
    -- populate OutputRoot.XMLNS.Envelope.PO.children
    --     from Environment.IXSB055PX[x].children
    -- ...
    SET y = 1;
    SET k = 1;
    WHILE (y <= Dtl) DO
        IF (Environment.IXSB055PX[x].CUSPO = Environment.IXSB066PX[y].CUSPO) THEN
            -- populate OutputRoot.XMLNS.Envelope.PO.PODetail.Item[k].children
            --     from Environment.IXSB066PX[y].children
            -- ...
            SET k = k+1;
        END IF;
        SET y = y+1;
    END WHILE;
    PROPAGATE;
    SET x = x+1;
END WHILE;

-- don't PROPAGATE again
RETURN FALSE;
