The article was indeed THAT good. I found it a few months ago and have finally been able to implement it in a project that I have duplicate data flow tasks in.
I've been trying to adapt my VS2013 SSIS project to the ParentSingleChildScriptMethod.dtsx. However it seems that using this method, the SingleChild.dtsx must be self contained. What I mean is that it can't use Project Connection Managers or Project Caches? The SingleChild.dtsx has to be able to function independently?
Thanks for any comments or additional information,
