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

 

It looks that help text for Stock Simulation for current period is
wrong. It should be the same as in module description. As Stock
simulation is made according to planning Stock Simulation is simply
Initial Stock + Planned In - Planned Out.

Other fields are used for calculation how many products to procure to
satisfy planning.

Already Out - all outgoing moves in state done
Confirmed Out - all outgoing moves in state confirmed
Expected Out - calculation: (Planned Out - Confirmed Out) (to see how many products you need to sell above Confirmed Out to satisfy Planned Out)

Already In - all incoming moves in state done
Confirmed In - all incoming moves in state confirmed

But there are some bugs fixed in my merge proposals waiting from
February. Anyway module will not work correctly for future periods until
another bug in stock module is fixed.

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.
