Tom:

Your solution gives me the following error:

SQL State: 42836
Vendor Code: -346
Message: [SQL0346] Recursion not allowed for common table expressions. Cause
. . . . . :   The common table expression specified is not valid. The
subselect for table TEMP_PSTRUC refers to itself. Recursive common table
expressions are not allowed. Recovery  . . . :   Change the common table
expressions to refer to a table that exists or a common table expression
that has already been defined. Try the request again.

Processing ended because the highlighted statement did not complete
successfully

Here is an SQL that works to start with.

WITH temp_pstruc (RELVL, ITEM, QTY) AS           
(                                                
SELECT 0, PINBR, 0                               
FROM AMFLIBP/PSTRUC  where pinbr like '%5022322%'
UNION ALL SELECT a.relvl + 1, b.cinbr, b.qtypr   
FROM temp_pstruc AS a join amflibp/pstruc AS b   
on ITEM = b.pinbr                                
)                                                
                                                 
SELECT DISTINCT *                                
FROM temp_pstruc                                 

Here is the resulting data, which is valid based on my source

 RELVL   ITEM                            QTY
     0   5022322                        .000
     1   7022322                       1.000
     1   7022322.1                     1.000
     1   10566.16                      2.000
     2   7022322.2                     1.000
     2   9022322                       1.000
     2   7022322.3                     1.000
     2   9022322.1                     1.000

It is not quite in the order that I want though. Does anyone know how to get
it to order like this:

 RELVL   ITEM                            QTY
     0   5022322                        .000
     1   7022322                       1.000
     2   7022322.2                     1.000
     2   9022322                       1.000
     1   7022322.1                     1.000
     2   7022322.3                     1.000
     2   9022322.1                     1.000
     1   10566.16                      2.000

Thanks.

   My browser is unavailable, but what about searching the web for examples
of recursive SQL queries to do that?  I seem to recall running across one or
two when trying to learn about recursive queries.  SQL is available on all
IBM i & i5/OS; later releases support recursive queries [with restriction to
the SQL Query Engine; SQE, which means query of the physical file(s) only].
