Hi.. I have been looking for a way to add stock to Items on my magento 18.104.22.168 without replace the old stock
First I tried to create a csv with sku and qty, and add data, But that only replaces the old stock.
example: The current stock is 10, and I want to add 5, so it should be 15 total. but after importing I get only 5.
How to solve this?
I allso found one script at
But It just does the same thing.. Overwrites the old stock..
Is there a simple way to do this ?
