Under REOPT=ALWAYS, when compiling an SQL statement that 
contains a subquery referencing a global or module variable, the 
following message may be returned even though the object already 
exists: 
 
SQL0727N  An error occurred during implicit system action type 
"6". 
Information returned for the error includes SQLCODE "-204", 
SQLSTATE "42704" 
and message tokens "<variable name>".  SQLSTATE=56098 
 
If the DBM CFG DIAGLEVEL=4 the following may also be returned:

If the value of the global or module variable does not change 
within the procedure, a workaround would be to declare a local 
variable to store its value, and then replace the global or 
module variable reference in the subquery with a reference to 
the local variable. 
 
For example: 
 
(Assume the existence of a schema S1 and a module variable 
ModuleA.var1) 
 
  call set_routine_opts('REOPT ALWAYS'); 
 
  CREATE OR REPLACE PROCEDURE s1.proc1(out V_ATTR int) 
  BEGIN 
    SELECT M.MVAR1 
      into V_ATTR 
            FROM 
                (SELECT 
                    ModuleA.var1 MVAR1 
                   FROM 
                    sysibm.sysdummy1 
                  ) M;-- 
  END ; 
 
  call s1.proc1(?); 
 
can be changed to: 
 
  call set_routine_opts('REOPT ALWAYS'); 
 
  CREATE OR REPLACE PROCEDURE s1.proc1( out V_ATTR int) 
  BEGIN 
    declare localvar1 int;-- 
    set localvar1 = ModuleA.var1;-- 
 
    SELECT M.MVAR1 
      into V_ATTR 
            FROM 
                (SELECT 
                    localvar1 MVAR1 
                   FROM 
                    sysibm.sysdummy1 
                  ) M;-- 
  END ; 
 
  call s1.proc1(?);
