I think the SEARCH DEPTH FIRST clause is required for the recursive CTE to properly expand the item are nested properly, and generate\establish a sorting column.

Of possible note, the recursive CTE is referred to as RCTE in the above article; i.e. possible value as a search token

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

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]. HTH.

I am looking for a program that will do a BOM Explosion and produce results that match MAPICS Inquiry AMEC72.

It needs to output to a file.

Someone did send me a program that will blow through the BOM, but the quantities don't match the MAPICS Inquiry AMEC72.
