Magento Stock (Configurable, Bundle)

Question

I have a website made with Magento, and a theme by me. The problem is:

The simple product with low stock is associated to a configurable product, and when i try to add a higher quantity of that simple product, it allows, and then, after the checkout proccess, we receive a e-mail from the store that there is a failure in the proccess like:

Payment operation failed:

Reason:
Not all products are available in the requested quantity

It occurs in bundle products that have a default quanity more than 1 too.

Someone can help me?

Thanks.

EDIT: Found this solution but i can't truncate my sales tables on database. I have all my sales records there, and there are a lot of them. I can't loose it. Magento: After ordering configurable product, its canceled because its out of stock

Answer 1

How many orders do you need to remove? If you got a handful that you can count by hand, you can try this solution to remove unwanted orders.

how can i delete test order from magento

It looks like it should work, but, as always, review the code and try it on one order first..
