I’m excited to be able to say that coming up next week on Thursday September 10, I’ll be presenting my session Power Pivot 101: An Introduction to the PASS Excel BI Virtual Chapter! For a lot of users, Power Pivot is like the Ferrari you had in your garage but weren’t aware and that’s one of the reasons I’m so excited to be able to present on this topic. This session is completely free and available to all who would like to attend. It doesn’t get much better than that!

Power Pivot is a powerful yet flexible analytics tool built into a familiar environment yet many users remain unsure of how to take advantage of this dynamic tool. In this session, we’ll discuss the purpose of Power Pivot, where Power Pivot fits within your organization and the basics of designing a Power Pivot model that integrates disparate data sources with the goal of gaining previously unrecognized insight into key business metrics.

This free online training event is scheduled for Thursday September 10th at 12 pm CST/1 pm EST. If you’re interested in attending, all you need to do is RSVP here to let the organizers know you’re coming. It’s going to be a great event, a lot of fun and maybe even educational! ;)

SSIS Denali Resolve References

One of the new features in SSIS Denali that I’m really excited about (Other than the ability to Undo ctrl-z) is the new resolve reference functionality that was brought into the product from the Parallel Data Warehousing team.  Resolve references is solving the problem that occurred when you created a package with a data flow and you made just about any change above your destination.  You would see red x’s on your transforms and to fix the problem you had to try and figure out what the below image was telling you:

If this has ever given you headaches before you will be please to find out with the release of the SQL Server Denali CTP that the resolve references tool will help.  To walk you through this first I’ll demonstrate the problem in the current version of SSIS and then show you how Denali’s resolve references eases the pain.

I have 3 sources as you can see above.  Each source is essentially the same:

·         Source 1 was used to originally configure the data flow. 

·         Source 2 is an exact duplicate of Source 1. 

·         Source 3 is the same but has one of the column names changed.

When you change from one source to another you get the dreaded red x and upon opening the Derived Column the Restore Invalid Column Reference Editor opens as usual.  The same would occur if I connect Source 3.

Resolve reference in Denali makes this easier.  Here’s the same example in Denali:

When I change from Source 1 to Source 2 in SSIS now in Denali it allows this without any problem because the sources are actually exactly the same (as you would hope it would react).

 

When I change to Source 3 I still have the red x problem I had in previous version of SSIS but instead of it being on the transform itself it is now on the data flow path.  This means you can actually fix the reference simply by right click on the path and select Resolve References as shown below.

Upon select the Resolve Reference button it opens a new dialog box that can be used for remapping your columns that have are currently invalid.  Like I mentioned this editor is very similar to the Parallel Data Warehouse adapters for SSIS.  The interface is very nice too.  It’s completely drag and drop to reapply your references as shown below.  When you finish your mapping you click OK and you can result development as normal!

Some other nice features here are:

·         Automap columns based on matching names

·         Filter under each section to find your columns quicker

·         Copy and paste the columns you have selected to be mapped to the clipboard

·         Delete unmapped input columns

·         Preview Changes before you confirm them

Hope this new features gets you as excited as I am about it.  I will try to continue to post new SSIS Denali features as I learn them myself.
