RE: Price Testing Inventory - Manufacturing
The cost that is rolled up to your finished manufactured product will be determined by the costing method you use for the raw material.
And as long as you for example use fifo as costing method for your raw materials and not use reservation there is no way you can really be sure what exact purchase was consumed in production of that specific finished item /finished batch. That will only be possible if you use some kind of item tracking.
With out item tracking you will have to relay on your costing method and trust that the system will keep track of what is the correct cost for the finished product according to the costing method of all your raw materials.
For example with fifo costing - the system will apply cost according to fifo - but with out item tracking you can not be certain that the physical inventory is handled according to fifo. There is nothing that will prevent the physical inventory handling of raw material differ from the costing methods handling of the cost as long as you do not use item tracking.
So you can create a report but it will be a theoretical report according to the defined costing method.
