Based on my knowledge, ERPNext does not consider real operation costs when calculating finished cost of products since the operating costs mentioned in workstations are not calculated automatically and after they happened, but they are only standard costs calculated manually by the user and before they really happen.
First, I’d like to check whether my understanding is right or not.
And second, I’d like to know whether any custom app or any kind of customization is available to cover my need? (i.e. the real production cost to be considered in calculating the finished product cost?)
