I´m not trying to generate several warehouse, the problem is that i have multiple locations in my warehouse.

example:
1. products for devolution
2. Damage goods
3. Products pending for delivery of clients online. (i dont delivery this products right away i have to wait for the truck to pick it up. this is why i set this location)
4. Products pending for delivery of clients of wholesale.

So the process would be the following:
if i made a sale online, the person in charge of inventory will look for the product and set it the location "pending for delivery clients online".

¿how would he know the locations of the products in the warehouse, for web sales?

The person in charge of the inventory will look into the system and see that the rout for this is the one set up in inventory.
1. Pick product from my location "warehouse general"
2. Move this product to my location "Warehouse web"
3. (expedition) Deliver this product to clients.

Conclusion: the issue i´m having is knowing which are the products that the person in charge of the warehouse will move to the location "Web sales". If any sale i make in Odoo through (website or sales module) are taking the same rout in inventory.

Intent of my response was to highlight the direct associations between product/ item (on a sale order line) to a route and Sale order (multiple items) to a WH in base Odoo. It was not to recommend setting up multiple WHs as a solution.

While your expected solution requires a relationship between a Sale order and a route, which isn't configurable without customization (server actions)

This association is also re-iterated in @Lars Aam response.

On a more specific note, your process of having to move items of an order to a dispatch location prior to shipping can be managed with multi-step (2-step) route. This functionality can be enabled from Inventory > Configuration > settings and then set on the warehouse Inventory > Configuration > Warehouse.

This would provide visibility into which location/ stage the order is in. Further you could set filters on the inventory operation to identify the type of order based on sales team.

Yet again these are concepts and not a solution, these need to be applied to arrive at a specific solution that meet your business needs (process & scale).

I think it is fully possible to configure operations and picking according to this requirement. There is a very high flexibility on the combination of:
- Two step picking,
- Source and destination location for operations and routes.
This configuration would be quite complex to set up. My approach to this would be to first make a drawing of the warehouse and where is the different locations. Then on the drawing indicate the different routes for the picking.
Decide wether you need two step picking. This is a setting on the warehouse.
Second I would define the operations needed. Then the rooutes and then the rules related to the routes. Each route can have different source and destination location.

The picking will tell the operator where to put what is for this picking. Wether you print picking lists or use picking withe the barcode app.

You mention damage goods. Managing damage goods is a different story. Odoo recommend using a separate location for scrap. You can register scrap during picking.
