Fixing incorrect inventory

["Robert Fraser" <..hidden..>]

Hi

I need to tidy up a SQL Ledger 1.1.12 instance where we are about to start using the inventory properly.  Over the years - SQL ledger then LedgerSMB - they didn't use the inventory and it is a bit of a mess (lots of negative inventory on various parts).

What is the best way of getting everything back to zero?

Is it the "opposite" of adding initial inventory, ie make an AP invoice with zero prices for the affected parts, and cancel out the quantities?

Thanks for any help
Rob
