[Bug 770186] Re: 'Stock Simulation' calculation issue

 

Hi,

I think it should take into account of Confirmed In, Confirmed Out. For example, with CPU1, I have
* at the time right before doing MPS calculation. Let's take current period from 20/Apr to 28/Apr
- initial stock: 5
- Confirmed In (already order suppliers in the current period): 10
- Confirmed Out (customers have already ordered in the current period): 20

* at the time of calculation, ex: 24/Apr
- planned in: 50
- planned out: 25

So Stock Simulation (stock at the end of current period): 5 + 10 + 50 -
20 - 25 = 20

Regards,

Title:
  'Stock Simulation' calculation issue

Status in OpenERP Modules (addons):
  Incomplete

Bug description:
  Hi,

  I'm doing tests on MPS (stock_planning). The tip for calculation 'Stock Simulation' in current period is
  (1) Stock Simulation = Initial Stock + Already In - Already Out + Incoming Left - Expected Out 

  However, module guide and actual calculation in current period is
  (2) Stock Simulation = Initial Stock + Planned In - Planned Out

  So there are 2 mistakes here. The first is consistent between guide
  and actual calculation. This is small issue. The second is calculation
  formula. Stock Simulation (stock at the end of current period) can't
  be formula (2).

  I dont know whether formula (1) is right or not. But I'm sure that
  formula (2) is not right.

  Regards.
