Magento 1.8 order product quantity per 0.1 decimals

Question

I'm using Magento 1.8 and I am amazed that I cannot get the system to allow orders of 0.1 quantity. I'm building this stor to sell fabrics, per 10cm's. So that would be 0.1meters and I do not want the quantity to represent centimeters.

I've tried the qty_increment field in the Admin > System > Configuration > Inventory but it only accepts full integers. :-(

Anybody know how to solve this or is Magento simply not meant for this ?

Answer 1

I actually found the solution, you CAN do this in the Backend by going to Product > Manage products > Select a product > Inventory > Enable Inventory > Enable Quantity uses Decimals > Stepsize 0.1 !!! SIDENOTE: Product price MUST be over 1 euro/dollar/any currency, or it won't work.

Answer 2

You cant solve this out by changing the product type to configurable. Kindly follow these steps to resolve this,

• Create an attribute "weight"(name as you wish) by ( Admin->Catalog->Attributes->Manage Attributes ).
• Create a configurable attribute set "Configurable_Attribute_Set"(name as you wish) by ( Admin->Catalog->Attributes->Manage Attributes Sets ).
• Assign the custom attribute(weight) to our new attribute set(Configurable_Attribute_Set).
• Create new product with new configurable type/assign this new set to existing product.
• Now, set the Inventory area default and set the quantity in the weight attribute(This allows you to enter decimal values).

Hope this helps.
