How to set a minimum stock value per combination

[patrmich]

Hi,

 

My shop is built with Prestashop 1.5.6.2.

 

I would like to do the following :

- set a minimum stock value per combination

- therefore when the current stock value for one combination becomes lower than the minimum stock :

    - the next supplier order would take into account the quantity required to reach again the minimum stock value

 

Thank you in advance for any suggestion.
