Comment 4 for bug 427733

I totally agree with Joel.

OpenERP has a curious and not real way to calculate expected receiving and sending date. Normally, system works based on delivery date you put on product form wich is not very usefull. System should calculate expected date depending on several parameters.

If you has got stock enough--> Delivery time could be inmediate
If you has not stock enough --> Delivery would depend on time your supplier expends on sending goods to you or time you expend on producing product. This production time should be calculated depending on time expended on each production process and time for each operation and again, the time your supplier expends on sending goods.

Additionally, the supplier expended time depends on him for EACH purchase order.

So.. the way today OpenERP calculates expected sending date is not usefull. We use to set it by hand on each outgoing and incoming pack.

Thank you:
