Comment 27 for bug 613286

+1 for a fix.

The current software I work with snapshots product costs at time of invoicing (or anytime it leaves the company)

All returns are by default based on this snapshot cost no matter how old. (Costs may be overriden by an authorized administrative user)

For our clients it is an essential. The accountants expect this behavior.

Particularly this is critical for "high" value goods that are maintained at low or zero stock levels.

One client handles plasma and lcd TVs. Their cost (and margin) varies by hundreds of dollars between purchases.

Returning a product, from an invoice, MUST reduce the reflect the original cost and associated margin.

Unfortunately this bug means OpernERP would not survive an audit with our current or prospective clients.
