New Post: Changing stock count in database

Hi everybody,

I've got a question, in case of a regular availability and a regular purchase, the number of the stock of the model for the selled product will be update with an automatic procedure (sp) or I have to do on my own? And in which status this should happen?

Another question is , and if I cancel an order the stock will come back to the previous state?

Sorry for my bad english

Thank you for your time.

Marco
