Thanks for the reply. I want to clarify that the "Validate Inventory" button is visible for the inventory user but when clicked it prompts an error message "Only a stock manager can validate an inventory adjustment"

How can I allow users to validate?

Hi, Just checked the function right now, Odoois checking the user group inside the code also. So you can't do anything from the user interface, you have to override the corresponding function and remove/bypass the user group checking in the code.

Thanks

Ok, from Edit View: form

<button name="action_validate" states="confirm" string="Validate Inventory" type="object" class="oe_highlight" groups="stock.group_stock_user"/>

I change it from groups="stock.group_stock_manager"/> to groups="stock.group_stock_user"/> but still not validating for user

Am I doing it the wrong way?
