Thanks for your reply.

But the problem if i import the same excel with different quantity the corresponding SKU not updated with new values. How can I achieve this. I just want to update the stock quantity for uploaded products using excel. And i don't want to click on 'Generate All Possible Combinations' every-time so i want include my stock quantity also using excel.

Please help me anyone

Thanks in advance.
