Problems with formatting in (Digital Metaphors) Report Builder

Hi,
i have problems with formatting in report builder - I have to print a master-detail report and do some calculations. In the master table there are records which do not necessarily have related records in the detail table (this is important for the formatting; i'll show by example). Each record in the master and the detail table has a field "amount to pay" and "amount payed". The first refers to the amount of money that is to be payed for this account, and the second is the amount already payed. However, the fields "amount payed" in the master table and the related field(s) "amount to pay" in the detail table are always 0 (so the record in the master table holds information of the amount to pay, and the records in the detail store information on payements for that account). I have to display the difference between the "amount to pay" and the "amount payed" (in the example i'll call that field "difference" ).

Example:
¨¨¨¨¨¨¨¨

  accountNo    "amount to pay"    "amount payed"  "remaining"  
MR   1             10000                 0           10000    <--(has no detail records)
  ------------------------------------------------------------
MR   2             50000                 0                    <--(has 2 detail records)
DR   2               0                 10000                  <--(first detail record)
DR   2               0                  5000         35000    <--(second detail record)
  -------------------------------------------------------------

MR - master record, DR - detail record


In the above example i showed how two accounts should be printed. As you can see the field "remaining" isn't printed in the first two records of the second example. The problem is: How can i set (which properties/code) the "remaining" field to achieve that effect? The problem is that i print the master record and then in a subreport the reamining related fields (if there are any, as in the second example). So, in the first example i should somehow evaluate if the subreport is empty and then simply display the value (10000); in the second, i should display the result only when also the related records in the detail table are printed (50000-10000-5000=35000).

I think i should use (well, i already use :-) two TppVariable fields - one in the main report's detail band (if there aren't any related fields in the detail table), and the other in the subreport's detail band, but the problem is how to corectly show and hide them.

Any suggestions would be GREATLY appreciated.

Thanx

Hi Mario,

at first, I think that would be good always place "remaining" in detail band instead of subreport and switch an appearence. It make report's format "fixed" and more readable. The problem is in counting value before details printed. I hope you can add some extra text in your SQL statement to calculate "remainig" for details. This is the way I would use.
