I have installed the product_extended module, and setup some base products. I have setup a "final" product, to be manufactured, and set it's Cost to zero. I setup a BoM for this "final" product (consisting of several of the "base" products, all of which are stockable products with cost setup in the product config), and through the Manufacturing module, built 20 of this final product.
When I attempt to click the "Mark as Done" button on the Manufacturing Order, I get the error:
The cost of <My Product> is currently equal to 0. Change the cost or the configuration of your product to avoid an incorrect valuation.
I have no "Calculate from BoM" button or similar on the "final" product config page - and the "Cost" field is now not editable, even while in Developer Mode.
I would like the Cost of this "final" product to be automatically calculated based on the BoM, and had thought the "product_extended" module would enable this feature. How can I accomplish this?
I am using Odoo 11 nightly builds - currently on build 20171127.
I may have figured this out -- originally had the "final" product set in a Product Category which used FIFO Costing Method, but after setting it to Standard Costing Method, I was given the "Calculate from BoM" button on the product config page.
However, when I clicked it, it presented a screen which had me manually enter a Cost, which wasn't ideal. I believe this is because I use FIFO Costing Method on my "base" products, instead of manually setting a Cost. When I run an Inventory Valuation, I am shown the correct value based on the PO pricing when received (as per FIFO Costing Method) for each base product, even though the "Cost" field on those products is set to zero. Perhaps I'd have to manually enter a Cost on each of these products to get the "Calculate from BoM" button to work automatically?
After entering a Cost on my "final" product, I was able to complete the Manufacturing Order, but I'm still unsure why the Cost isn't being calculated automatically?
