If you edit a legacy DTS package with SQL Server Management Studio, you may want to know how we can show the multi-phase data pump operations.
I haven't found an option to do this with SQL Server Management Studio. However, when you need to do something, you find a way to do that thing...
I found that necessary setting can be controlled through this registry key:
HKEY_CURRENT_USER\Software\Microsoft\Microsoft SQL Server\80\DTS\Settings
Our "multi-phase" data pump is controlled by DesignerSettings (REG_DWORD): if set to 1, the edit of multi-phase data pump is enabled in DTS Editor. Very hard to find... I also posted a bug here.
