  ABEND04E RC00E72018 at the location DSNXGRDS DSNXSMRE
  OFFSET4EAE(V9 only) could happen for an SQL statement
  referencing a view that satisfies all of the following
  conditions:
  
  1. It contains outer joins.
  2. It contains a table expression.
  3. The table expression contains UNION ALL and side-way
     references.
  
  An examples is shown below:
  
  CREATE TABLE T1 (
     C1 INT
  );
  CREATE TABLE T2 (
     C1 INT
  );
  CREATE TABLE T21 (
     C1 INT
  );
  CREATE TABLE T22 (
     C1 INT
  );
  
  CREATE VIEW V1 AS
  SELECT T1.C1
  FROM T1,
       TABLE(SELECT C1
               FROM T21
               WHERE T21.C1 = T1.C1
             UNION ALL
             SELECT C1
               FROM T22
               WHERE T22.C1 = T1.C1
             ) TX
       LEFT OUTER JOIN T2
         ON T2.C1 = TX.C1
  ;
  
  SELECT * FROM V1;
  
  The SELECT statement above will cause the ABEND.
  
  DB2 did not correctly process the aforementioned SQL statements,
  which caused the ABEND.
  

Problem conclusion

• DB2 has been modified to correctly process the aforementioned
  SQL statement, so there will be no ABEND.
