I miss the function in Odoo that the reorder levels (minimum qty, maximum qty, multiple qty) are automatically calculated for purchasing and production. 

For example, the number of products sold or products consumed within the set delivery time should determine the minimum stock. 

At the moment I'm doing it like this: I export the current report sold products and use it to calculate sensible reorder levels manually in Excel and then import them again. This can be somewhat automated in Excel using VLookup and preset formulas. 

However, it is still manual work and errors and discrepancies can occur due to renamed products or new products. 

I would be very happy if someone knows the problem and has a solution for it. Thanks in advance for your answers.
