Given your question and your remark that you do not want to use pricelists, the following options are available:

1. Manually update all records
2. Use a script to update the products, with the given rules about increase and rounding.
3. Create a new table, store the price and date in it, and use this to get the price of the product. This also requires you to modify product.product, in order to get the price from the new table instead of the product itself.

Option 3 is the best solution if you want to keep a history, but also needs the most mdifications.

You can configure Pricelist --> Pricelist Versions --> Pricelist Items for this. Select the category and configure rounding, margins, etc. as per your need with Based on as Public Price.

Thanks Priyesh,

But this is not the right solution. Our company (like others) work with a gross sales prices. Pricelist are discounted from the [product]-[sale price]. So I realy need to update the [sale price] in the [product view]
