Please everyone, adding more comments with "I agree with the others" will not help, they will just be ignored.
If you want to make a difference, please show that you have looked deeply into this issue and have some real technical/business feedback to provide about this.

What we are trying to explain here, is that this bug relates to a
feature that is very dangerous, and Fabien has tried to give a list of
the many things that can go wrong in comment #21.

Your numerous comments show that you already have different opinions
about what this should do, some people are even suggesting that this
should automatically update the cost_price *and* sale_price of related
products?! Really, does everyone realize all the possible dangerous and
hidden things that this could do to your accounting and stock
valuation??

This is the reason why we think this feature should not be available by
default (e.g in an extra module), and the people using it need to fully
realize all the implications.

If you still think this is wrong, then please explain properly what you
would expect the system to do in all situations. This could be done with
a real example that includes products with multiple BOMs per product and
multiple levels, and taking into consideration the stock valuation in
accounting: manual *and* real-time!

Based on this, we could discuss "seriously" what to do, and decide if it
makes sense to provide this feature in the core of OpenERP.  [ On this
bug or on bug 747056 ]

Title:
  Cost price calculation limited to 2 levels in product bom

Status in OpenERP Modules (addons):
  Invalid

Bug description:
  A concrete example better than a long and difficult explanation :-)

  We have the following product A composed of the product B and product B is composed from product C. So the below BOM:
  A
  -----B
  -----------C

  If the price of B is modified, then the price of A can be also modified.
  But if i modify the price of C, only B is modified and not A.

  This is a very important blocking issue, since in most of the real prod environment, we've of course more than 2 level of boms (in some customer installation, up to 100 levels !).
  So any modification at the bottom should have a consequence on all the bom structure until the top, else OpenERP cannot be used for production.
