ACS Run SQL Scripts bug?

Getting an error with the following:
select *
from vaiconvml.mvvendms ap
full outer join vaiconvml.vorvendmst iv
on ap.vvndno = case iv.vapvno
when 0 then iv.vvndno
else iv.vapvno
end;

The error is
##### Parsing error at line 7 #####

The above works fine in the green screen Run SQL Scripts and in iNav's Run
SQL Scripts.

Apparently ACS's Run SQL Scripts is trying to parse the statement before
sending it to the system.
