Team, I have an issue that is perhaps the most irritating part of using EDT (when for example compared with the SPSS Modeler), not from what I can do with the tools and the fact that they aim to different audiences, but from a data workflow stream integrity management. Allow me to explain:
With SPSS Modeler whenever I build a stream / flow, unless I make source or column related changes, the tool always keeps my nodes / transformations the way they are even if there are merge / joins, etc.
In EDT I have a lot of issues in this area: very often I find out that I need to make some small changes in ifs and filters transformations and they end up re-setting many of the downstream transformations and I have to literally be re-building halft the flow - even though I did not change ANYTHING that should be affecting the stream integrity.
You probably will need an example and this is one. I am not quite sure why changing an IF statement, affects some of of my joins and other transformations after that have completely unrelated keys.
