When we mark opportunity close as loss then too we get option to add actual revenue, what does that mean, We enter estimated revenue at start and then as per quote line items actual revnue gets calculated. When we do close as won, we get option to fill actual revenue. I thought when we won at that time we need to know what we going to earn, at time of loss how can we know what actual cost could have been for work, there can be more need of prods while working. And what significance it carries to put actual revenue when we close as loss. If its loss there has to be no revenue at all. Estimate is fine but actual should be always zero. Please guide with this concept.
