Hi Mlauri,

More details would be more helpful.

The better way maybe extending the price list with custom module,  add more option  on "base price" selection option, such as "last purchase cost", add the last purchased cost in product model and form as compute field, than extend the pricelist calculation method 

I think price depends on supplier pricelist is not good way. Bcoz you have lots supplier pricelist and have some supplier pricelist imported but still you haven't purchased anything from them. So it creates some issue. Good thing is depends on  your current inventory cost price and configure proper costing method. 

I don't know how it creates conflict with inventory valuation.

Hi Thomas,

I've defined a new kind of "base price".

It's quite easy.

Let me know if you need more details.

Hi Michele,

did you find a solution for your problem? I'm facing the same issue and haven't found a solution yet.

Thomas
