Please check landed Cost module bu one of the partner and it is doing exactly what you expect here.
Let me know if you don't find it.
Thank you Sid for this information.
In fact I've installed the module and started to work on it. However, I have some questions or better said ambiguous points:
1- I've noticed 2 new fields added for the landed cost calculation in the product form (in the 2nd tab "procurement & locations" - "Miscellaneous" part), what does each of these 2 fields ("Distribution Type" & "Calculate Landed Costs") signify? Should I check the "Calculate Landed Costs" checkbox only if I want a certain product's landed cost to be calculated depending on the purchase orders + any additional costs (such as custom fees)?
2- I noticed that when I create a new landed cost, it's being created as a new product. What are the information that I should fill for this kind of product? What's its product type (Consumable, or service)? What is it's cost? Should I check the "Calculate Landed Costs" checkbox? What is its "Distribution Type"?
Is there any guide for the usage of this new module?
