Hello friends,
how would I create time line data of my stock - ideally as a graphical display, or as numbers to be fed into LibO? Meaning: Whenever the amount of items in stock changes, a new number and the corresponding date should be available.
Hope I was clear enough…
Cheers,
Wolf

You can use [Product Quantities by Warehouse](https://docs.tryton.org/projects/modules-stock/en/latest/design/product.html#product-quantities-by-warehouse) which is available as relate of product (see [Product Quantities By Warehouse (Computer)](https://demo6.0.tryton.org/#demo6.0/model/stock.product_quantities_warehouse;context=%7B%22product%22%3A%5B17%5D%2C%22context_model%22%3A%22stock.product_quantities_warehouse.context%22%2C%22stock_skip_warehouse%22%3Afalse%2C%22warehouse%22%3A5%7D&context_model=stock.product_quantities_warehouse.context&name=%22Product%20Quantities%20By%20Warehouse%20(Computer)%22&views=%5B315%2C316%5D))

Thank you. I tried to find out how I can call that feature [Quantities per warehouse](https://demo6.0.tryton.org/#demo6.0/model/stock.product_quantities_warehouse;context=%7B%22product%22%3A%5B17%5D%2C%22context_model%22%3A%22stock.product_quantities_warehouse.context%22%2C%22stock_skip_warehouse%22%3Afalse%2C%22warehouse%22%3A5%7D&context_model=stock.product_quantities_warehouse.context&name=%22Product%20Quantities%20By%20Warehouse%20(Computer)%22&views=%5B315%2C316%5D), but finally have to give in.
Could somebody give me a hint?

I don’t understand your question. When I click the link, log in with the credentials for [demo](http://www.tryton.org/download#demo), I can see the quantities of a product named “Computer” in a warehouse named “Warehouse” over time.

From the product tab, there is a “relate” menu entry named “Product Quantities By Warehouse”.

Thank you very much, Cedric. I would never have found the feature there on my own, but it’s precisely what I’ve been looking for.
Is there a way to get out the underlying numbers to process them in a spreadsheet?

You can switch the view for a list and you can export the records as CSV.
