Everything you use in Sheet-B has to be generated in Sheet-B. We don't pass measure results from sheet to sheet. (We CAN pass dimension values through a filter action.)
The best way I've found to generate values from Sheet-A in Sheet-B is to make the filters from Sheet-A apply to Sheet-B. Use the same calcs, etc. You don't have to shape Sheet-B like Sheet-A. Just have the same dimensions on Sheet-B, even if they are just on the Details shelf.
