How to use for Configurable Products the quantity increments of belonging simple product

[christoph_gaetje]

Hi,

i want to set up configurable products. The problem is that the simple products have different packaging units and magento uses the quantity increments of the confi product not of the simple one.

Magento 1.9...

Anybody knows how to change that, or any extension which is doing this?

Thank you in advance

Christoph
