A query about price matrix code

[Nigel Titley <..hidden..>]

Folks,

I've written an oscommerce-ledgersmb bridge and it largely seems to 
work. At the moment it does the following:

1. Creates new parts in Ledgersmb based on items in oscommerce, 
including price matrix
2. Creates new customers in ledgersmb based on oscommerce
3. Creates new sales orders in ledgersmb based on orders received 
through the web site.
4. Updates website  parts inventory based on ledgersmb.

It runs as a regular cron job at whatever frequency you need. The only 
downside is that website inventory may lag real inventory.

I'm just about to start using this for real. I'm migrating my accounting 
system from gnucash to ledgersmb and during the testing I've come up 
with a problem with price matrices, which may be just my 
misunderstanding, but I can't seem to find what I am doing wrong. 
Basically, I create a generic price matrix for a part (no  pricegroup, 
no customer specific) with breakpoints at various values. When I 
manually create a sales order or a quotation with a quantity that should 
trigger the price break I don't get a price reduction, just the basic 
list price. This happens whether I have entered a part with a price 
matrix manually, or via my bridge.

I'm running LedgerSMB V1.2.16 on Ubuntu Hardy. If this is a known 
problem, please accept my apologies and point me at the documentation.

Many thanks

Nigel
