I'm not sure I completely understand. However, if you place both Invoice Date and Cheque Date on the rows shelf (in that order), then create a calculated field similar to the following and place it on the view:
window_sum(sum([Cheque amount]))-sum([Cheque amount])
Once it is on the view, right click on it and select Compute Using>Cheque Date.
If this does not help, could you provide more information on what the desired results are?
