By using list_price_used we are sure to have a list price in the company currency so there is not need for conversion. Also list price of a product can be empty so we should not try to round it. Closes #13110
Project Revenue Module ###################### The project revenue module computes revenue and cost per task and project. The revenue uses the list price of the product. If the product's unit of measure is time based, the revenue is computed as the product of the price and the hours of effort otherwise the price is considered as fixed. The cost is computed by summing the cost of all the linked time sheets and the linked purchase lines.
