We installed Panorama Nova View Flash 6.2.5 and wanted to use it to connect to PowerPivot. While beginning the work, we couldn't connect to the PowerPivot files and would get an error message. My colleague Tomer Horev was in charge of SharePoint installation and also found the following solution. We understood what the problem was through the help of Panorama support. We tried to connect to the cube that's created for our PowerPivot file through the Management Studio. That meant connecting...
Microsoft recently released a CTP of Power View on SSAS Multidimensional , (and yes, I know I'm a bit late writing about this, but I still wanted to give my two cents on it). So we're edging closer towards the point where Power View and Excel will be able to cover all of your viewer needs (or at least most of them :)). Years ago when I wrote about Report Builder on a cube and all the problems that that relationship created, I wondered when that would be fixed. Now that we have Power View...
I had a new measure to add to my cube a new measure. My fact table up till now was with a monthly granularity. I assumed that I would have to define a scope in MDX for the intermediate period and the monthly period. I connected the fact to the year level in the Period dimension and got this message: If you select a non – key granularity attribute, the server will not be able to aggregate data properly unless you make sure that all other attributes are directly or indirectly related to it by specifying...
Not too long ago my boss Yaniv got a telephone from one of our customers saying that he thought a cube was missing some values from it. The thing is that at first that didn't sound logical to us because usually we would get an error on that. We expected the process of the cube to fail, or something of that sort. But not this time. Now, there's a few reasons why there are rows missing from a cube as recently blogged by Richard Lees. But our reason was slightly different. We were using a view...
This blog is SUPER SUPER excited, because for the first time, after four years, we have a guest! I met Mr. Kobi Deutsch in the SQL Explore Convention held about two weeks ago. During a session we both took there, he mentioned something I wasn't aware and I thought maybe I'd bring it to you as well. So, I'm leaving the stage for Mr. Deutsch: Sometimes, when we check the MDX requests in the Profiler, we see that there is a partition that was scanned and loaded into memory although it is...
I recently opened a new project in SSAS 2008 R2. After finishing developing the cube, I deployed and processed it on the server. I got a really weird error message that meant, unfortunately enough, nothing to me: " Key cannot be null. Parameter name: key " So what's a girl to do? Well actually, I remember that every so often when I was developing a cube, I would have a problem with the data connection. The default I had defined for me when I opened a new connection was .Net Provider...
A colleague of mine ran into a peculiar problem with her cube. She deployed it just fine and didn't get any error messages. Still, there was a problem. She could see the dimensions in her SSAS project just fine. She could see her cube as well. But she couldn't see any of her measure cubes. So what was the problem? She was missing the calculate statement from her cube. If you look in the BIDS at your cube on the Calculations tab with a Script View, you'll be able to see that the first...
I wrote a post a while back about the pros and cons of developing a Report Model based on a cube . I got two comments on it telling me to check out Intelligencia . I decided to look into it, and what can I say? I'm impressed... Intelligencia is an add - in to Visual Studio which helps you build Reporting Services Reports on top of a cube. Those of you who have tried doing that in the past with what there is, probably remember that it wasn't terribly comfortable all of the time... First example...
I found myself revisiting the Parent Child dimension quite unexpectedly. I'm working on a project which involves the division of the city to different statistical areas. The division of the city into these different statistical areas happens once every 10 years or so, according to the changes in population tracked by the municipality itself and the government in the Census of Population and Housing. Up till now, my cube had in it just the statistical areas distribution from one Census onwards...
Almost every post I made about Report Builder, be it the pros and cons of creating a report model on a cube or refining a report model based on a cube, brought the same question - what makes reports based on a report model to break and how can you avoid it? Well I didn't know the answer as I admit it never happened to me, (sigh of relief), but the question did bother me enough for me to try and research it a bit more on the internet. And yes, I'm happy to say there is more than enough information...
Creating a Report Model based on an Analysis Cube – Pros and Cons If you follow my blog, you probably know by now that I developed a report model based on the Analysis Services cube I already had. I even got around to updating the report model . And then, my users started using it. And you know, whatever we do just seems so wonderful to us, until our users find all sorts of flaws with what we did… so yes, my users did open my eyes to quite a few problems that may occur when you build...
Well I thought today we'd go over visual totals in MDX and also see how they may have an impact on how you assign role based security in you SSAS project. Visual Totals in MDX are there to give you just what they describe – a sum on the children in a certain set. Child members which are not in the specified set will be ignored during the calculation. For instance, if I have a set that consists of: USA, New York, Washington and California, when I look at the total for USA, I will only see it's...
I have recently discovered a brand tool to help me better understand my work. It's a free tool from the Microsoft SDK . Specifically, I'm talking about the Rowset Viewer . The Rowset Viewer was intended for you to "view and manipulate OLE DB rowsets, with the added ability to call and manipulate other OLE DB methods from the data source, session, command, rowset, transaction, and notification objects supported by any OLE DB provider." I found myself using the tool so as to understand...
Well I guess congratulations are in order because I finally got around to using a report builder in my project. Turns out that building a report model based on a cube is as easy as 1-2-3. Still I had a problem, as for some unknown reason the translations were showing for my dimension names and my measures, but not for the dimension's attributes... At first I thought maybe this is a problem solved by Service Pack 2 (as my tests were done on a Server with Service Pack 1). Alas, no. So, a further...
A Parent - Child Dimension is a special sort of dimension, to be used in case: You have data even for non – leaf members. For instance, you may have set – up costs allocated for the Category level (the higher level), but profit data for your Product level (the lower level). You have an unbalanced hierarchy. The classic example for this might be the Geographical Hierarchy which at times might look like: Country > State > City, and at other times like Country > City. For an international company...
