I try to enter cost\_price for products but I get the error message: You cannot change the cost price for a product which is associated to stock moves. You must use the "Update Cost Price" wizard. How can I enter the cost price for products that I have already in stock at the begining of the period? (I imagine that products that are purchased will have their cost price computed from teh pruchase invoice). ---

I tried and I do not have any error message. There is just a know issue between this wizard and the re-computation of the cost price: [Conflict between wizards "wizard\_recompute\_cost\_price" and "wizard\_update\_cost\_price" (#7273) · Issues · Tryton / Tryton · GitLab](https://bugs.tryton.org/issue7273) ---

Here is my error. I used the action “Recompute cost price” on the Product. I was not able to find an “Update cost price” wizard anywhere ;/ Could you please point me to it? ---
