Thank you for the response. I really do appreciate it.

I suspect I will never understand the logic behind product.product, product.template and variants. They seem to be unnecessarily messy. 

In regard to the count, I understand that each location can be grouped and assigned to a storeperson. What I have noticed is then there are only 883 products in total listed in the inventory adjustment page. There are almost 1600 Storable product items in the catalogue. I'm unclear about what happened to the other 717 odd items. 

I can see the full 1600 items from Inventory > Products and apply a filter on Storable Products.

Hi,

Everytime you create a product in Odoo you actually create a Product Template (product.template). The same information will also be stored in product.product, which is your actual product. Product.product is used for your variants. Each variant is a individual product in product.product. I hope this clarifies :).

When you want to do an inventory count you can use the Inventory app > Operations > Inventory adjustments. What you could do is group the list by the locations you want to have counted by different people. For example Group by > Location, if every location has another storeman. You select the (group of) products that you would like to be counted by this person, and then click on Request a count. In the popup you can select the person responsible for the count.

If you don't want to use the Odoo UI you can also export this data and import later. Select 'I want to update later' in your export popup, and export the details your storeman needs to do the count. Also include the field Counted Quantity and use this to import later again. When you import the file i would only import the external ID and the Counted Quantity field. After import, you can Apply the count. 

I hope this helps!
