How did you import the list? I am currently importing a whole list of items as well, using a script and the OE framework. I have not seen this issue at the moment.

It isn't necessarily wrong. OpenERP has a double entry stock management system. It can't increase inventory in your location without decreasing it at another location. Once you are up and running, the other location would be your Suppliers.

Thanks Ray; I know understands that the stock journal is there to keep track of the moves; it is not an "accounting journal". Is that right?

Correct. What you probably want is what you get when you check the box next to 'Generate accounting entries per stock movement' under Settings --> Configuration --> Warehouse and configure your inventory valuation accounts.

Absolutely! This is what I need. And I am still confused about how to setup parameters, namely in Stock Journal; perhaps no parameter to pass there! Your advices would be greatly appreciated :)

I've never set anything on the Stock Journal. Check out http://doc.openerp.com/v6.1/book/5/5_14_Stock/5_14_Stock_financial.html and narrow your questions a bit.
