Creating a Reporting Services Subscription

12 days ago by DevinKnight  -  Comments: 0  -  Views: [391]

Subscriptions are a great feature in Reporting Services that will run a report unattended and deliver it to users either by email or Windows File Share. Subscriptions can also be scheduled so if your end users need a report monthly you can automate the delivery process. The steps given in this article will show you how to configure subscriptions using the Windows File Share delivery method. Before you start to configure your first subscription make sure to have the following taken care of first:...

Optimizing Power BI Q&A with Synonyms and Phrasing using Cloud Modeling

24 days ago by DevinKnight  -  Comments: 0  -  Views: [1650]

If you’ve have used or even just seen a demo of Power BI Q&A you’ve likely seen there’s great potential in the feature for even low-tech user. I usually say, “If the user knows how to use a search engine then they can interact with Q&A.” You can read the basics of how Power BI Q&A works from my previous post here . While having this capability is great it can take some fine tuning to perfect for users interacting with it. Power BI provides you with the a...

Custom Auditing and Error Handling in SSIS

9/10/2014 by hardikabhavsar  -  Comments: 0  -  Views: [5601]

Errors can occur at any stage when you extract data from source and load it into destination. You must include error handling method for your package to test and troubleshoot. There are several ways to handle it at different levels during your process. Either you can use default features provided by SSIS or you can develop your own method to handle the error. Ex: at a control flow level, if an error occurs, you can add a failure constraint and redirects the workflow to an alternate task. In data...

Analysis Services Partitions

9/5/2014 by DevinKnight  -  Comments: 1  -  Views: [1171]

Partitions are a great feature in Analysis Services that allow you to split measure groups in to separate physical files. All measure groups by default have one partition but by splitting that partition you will gain improved query and processing performance. Partitions can be split in any way you see fit. Many people choose to separate measure group data by date. This makes sense because just about every fact table is going to have a date dimension associated with it. It also makes for a clear ...

Analysis Services Dynamic Security

9/3/2014 by DevinKnight  -  Comments: 0  -  Views: [786]

Imagine you have a requirement to capture the user accounts that log into your cube and based on their username they will only be permitted to see specific data. This can be accomplished by creating dynamic or table based security in Analysis Services which is much less difficult to setup than it sounds like. In this article I will walk you through the setup needed on the relational database side as well as Analysis Services side to get this working in your environment. You will start by identif...

MDX Time Calculations Built to Scale

8/14/2014 by DevinKnight  -  Comments: 2  -  Views: [1207]

When creating time calculations in Analysis Services you may take several approaches. For people that have just begin learning SSAS they likely have spent several days writing calculations that return things like year to date, rolling twelve month, and period over period for every measure they have. For the more adventurous developer they have tried using the Business Intelligence wizard which automates the process of writing time calculations on selected measures. It creates an attribute in the...

Writing Parametrized MDX for Reporting Services

8/4/2014 by DevinKnight  -  Comments: 0  -  Views: [993]

Writing MDX inside of Reporting Services has been the nemesis for many report writers for far too long. If all you need is the Query Designer to create a drag and drop datasets then it’s a piece of cake, but have you ever wondered what’s going on with all the MDX that the Query Designer creates. Or how about how do the parameters work that it creates inside MDX. I’ve heard many report writers that use Analysis Services as a data source (including myself) say it is too difficult...

How to Pass Multiple Values from an SSAS Report Drill Through Action to an SSRS Multi-Value Parameter

8/1/2014 by DustinRyan  -  Comments: 0  -  Views: [5238]

These past couple weeks I faced a client requirement to create an SSRS Report Action in an SSAS cube. This requirement dictated that a user should be able to browse a cube in an Excel pivot table and be able to drill through to an SSRS report (which used SQL Server as the data source) and view data at a monthly level. The twist was that if the user drilled from a year or quarter level, the appropriate months would be selected by default. I thought the solution I came up with was useful so here y...

Script To Populate AdventureWorksDW DimDate

7/17/2014 by DustinRyan  -  Comments: 6  -  Views: [905]

I do quite a bit of training for Pragmatic Works so I find myself working a lot with the AdventureWorksDW data warehouse database. AdventureWorksDW is a great test database if you're wanting to demonstrate a concept or test a theory, but one of the things that has always bugged me is that the date dimension (dbo.DimDate) has holes in the data! Having a complete date dimension is important when working with SSAS. Well yesterday was the final straw, so I put together the following script that will...

Understanding Analysis Services Relationships using Dimension Usage

7/15/2014 by DevinKnight  -  Comments: 0  -  Views: [2652]

As a part of designing an Analysis Services cube you must define how each dimension is related to each measure group in your cube through the Dimension Usage tab. The Dimension Usage tab is found when editing the cube in the cube designer. The screenshot below shows dimensions on rows and measure groups on columns. The points at which they intersect define how they are related. These relationships are automatically defined when the two objects (measure groups and dimensions) are added to the cub...

How To Display 0’s Instead of NULL in your SSAS Cube & MDX Query Results

7/15/2014 by DustinRyan  -  Comments: 0  -  Views: [1992]

I've done a decent amount of SSAS and MDX query development over my career and one of the requirements that continually pops up is to display zeros instead of NULL when browsing the cube. Take the following query as an example: Select {[ Date ].[Calendar Year ].Children} on 0, NON EMPTY {[Geography].[ State -Province].members} on 1 From [Adventure Works DW] Where [Measures].[Reseller Sales Amount] And here are the results: There are a couple ways display 0's instead of NULL. The first way is to ...

Using a Hyper-V VHD in an Azure VM

6/19/2014 by DevinKnight  -  Comments: 0  -  Views: [2557]

I’m in the process of moving some my lab environments that I use for teaching SQL Server classes to Azure. I’m pretty new to the Azure infrastructure world but I thought I could share some of my lessons learned in doing this. My first post will walk you through moving an existing Hyper-V virtual machine image to be hosted in Azure. Limitations Before you start this process here’s a couple things to be aware of: Virtual Machines in Azure must be .vhd files. They cannot be .vhdx ...

Reducing the Disk Size of a Hyper-V Virtual Machine

6/19/2014 by DevinKnight  -  Comments: 0  -  Views: [2116]

Have you ever created a Hyper-V virtual machine and later needed to change the size of the disk on the VM? When you initially create a virtual machine you provide a size for the virtual hard disk (as shown below). It’s pretty straight forward to expand the size of this virtual disk but if you need to shrink the disk size there’s a few extra steps to make the change. Here’s the simple steps for expanding a virtual disk: To expand a disk you can go into the Settings of your virtu...

Power Pivot as the Core to your Power BI Solution

6/3/2014 by DevinKnight  -  Comments: 0  -  Views: [1404]

I’ve noticed a recent trend with many presentations and articles on Power BI and Excel functionality. Many of these presentations show how quickly you can take tools like Power Query to find and discover data and then quickly present it through tools like Power View and Power Map. These are really impressive demonstrations of what you can do in Excel in a matter of a few minutes to start with no data to quickly making business decisions through some form of a reporting layer. While I reall...

Power Query to HDFS – Remote Name Could Not Be Resolved

5/2/2014 by DevinKnight  -  Comments: 0  -  Views: [2008]

I wanted to share a quick resolution I had to a problem with connecting Power Query to data stored in HDFS. Seems easy enough. Launch Excel and through Power Query select From Other Sources –> From Hadoop Files (HDFS) Next you’re prompted to provide your Hadoop server name then click OK. I’ll be using the Hortonworks Sandbox environment for this demo. I then see all the files available on HDFS. If I try to explore the data in these files by clicking Binary next to any of the...

Thanks to all who attended yesterday?s webinar. Since I ran short on time and wasn?t able to answer any questions, here are all the questions and their answers. Q: Does the lookup transform require the data (join key) to be sorted? A: No sorting required. The Merge Join requires a sort, but not the Lookup transform. Q: Could you have used "False"? A: This was a question in regards to an SSIS expression that was used to check a boolean value in a column. In the expression I used ?0? to represent ...
