The next version of SQL Server (codenamed katmai) is currently in the planning stages so if you want new functionality to be included, now is the time to get your requests into Microsoft via Microsoft Connect.
There are many areas that can be improved in SSIS (and I have previously mentioned some of them here and here) but I think one of the areas in which we are going to see big advances is in the area of package debugging. Currently package debugging facilities are pretty good - but they could be better.
Would you welcome the opportunity to be able to do any of the following?:
If the answer to any of those is "Yes" then click through and add some detail to the Connect article. The more people that ask for a feature, the more likely it is to appear. Also, the better quality the customer testimonials are the more likely it is to appear as well. So get clicking and get commenting. Help to make SSIS a better product!
Do you have any more ideas? If so, post them onto Microsoft Connect and reply here with a comment. Get people voting on them.
