Re: BOM Explosion

Chuck-

Thanks for this information. That pdf has some great info on the RCTE's. It looks like it is only with V5R4 and later releases.

On another point, you can do recursive overview cards in PowerLink (at least rel 7.7).

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.
