I've been trying to find a solution to trigger process to assign stock counts to employees based on product. 
For example: Go count all of Product A (multiple locations)

I have tried setting up a server action on model product.product that will "Execute existing action".
This points to another action that will "Update Record" and runs on Model stock.request.count and will Update the record.

The current behavior when I click on the context menu in the product page nothing will happen and no inventory adjustment is assigned in the Barcode App.

Is this possible? Am I missing any steps?
Once this works id want to try and automate this server action.
