I've taken over for another developer. Unfortunately he left in such a hurry, he was not able to pass back a whole lot of info about what he had done and what he was working on.
One of the things he did, it seems, was to create using technologies just to say he used those technologies. One of these is SSRS. Most reports currently used are Crystal Reports, but there are a couple that were created using SSRS. Unfortunately, at least one of these needs to be modified. Fine. I took a three day course in SSRS back in 2004. It was similar (sort of) to Crystal, and I don't think it's changed that much. :-)
Unfortunately the one problem I have is where to find the report file (the "rpt" file, if it were Crystal Reports). Our network is pretty vast, but there are not too many places where it may be, but I need to know what to search for.
In my opinion if you are experienced in Crystal, then SSRS should be a pretty manageable learning curve.
