You can use your inventory stock management software to view your current inventory stock group, sorted by vendor. This way, you can easily and quickly access information about the vendor supplying each item.

Please guide, I can't find "Inventory Control" option in the mentioned menu.

Yes, it is possible to get the current inventory stock group by the vendor that supplies an item in Odoo. Here are the general steps you can follow to get this information:

1. Go to the Inventory app and click on "Inventory" and then "Inventory Control"

2. Under "Inventory Control" there is an option to filter by "Product" and "Vendor"

3. Select the products you want to check and the vendor that supplies them.

4. The inventory report will show the stock group by vendor

You can also create a custom report that shows the stock by vendor, you can do this by creating a new report in the Reporting app, and then use the fields 'product' and 'vendor' to group the stock.

Alternatively, you can use the Inventory valuation report, which shows stock by warehouse and by supplier, this way you can check the stock by vendor.

Please note that the above steps are general, and the process may vary depending on the version of Odoo you are using and your specific setup. You may need to consult the documentation for further information on how to set up the inventory reports in Odoo.
