Standard Cost Estimate with Quantity structure - without BOM
I want to run Standard Cost estimate without BOM. I am having only activities. For example... I am manufacturing OXYGEN by taking the natural air. Natural air I am not maintainingin stock... it is not a material for me. But I am having different activities for manufacting OXYGEN.. I want to run standard cost with only routing... How can I do it? I tried.. but system is giving a error saying that "No BOM elements with relevancy to costing"
Thanks in Advance.
