Implicit session required for rollback or commit

  Explanation:  You called a procedure that tried to commit or
  rollback the implicit session's implicit transaction when the
  current session was one other than the implicit session.  This
  could be accomplished by calling a procedure that does a
  rollback or commit that was compiled without session support or
  from an RDML/RdbPRE module.

  User Action:  Define an SQL module procedure to Rollback or
  Commit and compile with session support enabled.
