title: SSRS reports - functionality reuse
body: <p>Every month there is a bunch of new reports delivered to customer.
  And I am really starting to be pissed up and I am thinking about buying long whip on developers. The first problem is: I am quite newbie in SSRS, BIDS. I have OOP paradigm experience.
  The second problem is: There is some functionality, that is always the same in every report. Like calculating YTD, YTD for current period (you are right, it is wrong we do not have this in OLAP, but with present state of project it is more realistic to win jackpot than do this change), exporting reports etc. And every second report has this wrong.</p>
  
  <p>So, with my optimistic view, there could be some approach to solve it in the OOP like aproach. Like do some report from which all reports will inherite or something like this.</p>
  
  <p>Any suggestions?</p>
