Can anybody show me how to create a Calculated Item in a pivot table? I have a field called CLASS with the following values: Stock, Sales, Order and Target. I would want a field that calculates Stock minus Order. As per HELP, we have to ungroup each item and enter the calculation. I have done that but have never been successful in creating one. Either the system hangs up or I get a message that Calculated Item should be of the same field, which was how I defined it.

Am I the only one who is having problem with this?
