Can someone explain to me how lineage works in IS? Where does one start? how does it figure out the data source?
Let's say I'm completely ignorant of how this works and how to do it (because I am), can someone fill me in?
I've looked through the Admin and End User docs and haven't found much. So if it's in there in detail, please point me to it.
The more you can provide or explain or point me to, the better.
I have InfoStew 4.2.
thanks in advance.
Please check the IS user guide : http://help.sap.com/businessobject/product_guides/sboIS42/en/is_42_user_en.pdf
It has examples on how to view lineage\ read lineage diagrams - e.g. a column in webi report is pulled from universe based on a data source that is populated say by Data Services.

I guess what I'm really wondering is how is lineage established. I think of it as "here is column1 in table1 and it's original source is column6 in table8". Is that not what IS lineage does? And if it does, then how does it establish such a lineage. Just because I scan system1 and system2 - getting all their tables, columns, views, etc - doesn't automatically establish any "source links" between the two, if they exist. Or does it, and if it does, how? What is the key to establishing a lineage? Or am I defining the term incorrectly?
thanks for any insight.
Hi Ken,
The best way to explain how the lineage is created is by making it simple. You have a Mother and Father maybe some siblings. They are all part of your lineage.
The same holds true for the lineage of whatever object your looking at. For example if you run an integrator from Metadata Manager against a BI Enterprise Repository. You should get all the reports and all the lineage that it took to create that document.
Report>Universe>Objects>DSO>and so on.
The integrators are explained in detail by the company that creates them for SAP/BO.
Take a look. http://www.metaintegration.net/Partners/SAP.html
Hope this helps.

Yes if you're looking for the items that I listed in my last post.
You can run a relational crawl on any database then make associations between them to get the lineage that maybe you're looking for.
Sounds like you need to look into the MITI site and look at what your trying get for the end result.
Thanks,
BW
Ken,
It sounds like to me you need some training. Rather then me telling you. You could go through interactive training here.

You should also follow the following pages.

Meet the expert
They cover a lot of how topics.
Thanks,

Give this a try. There's a lot of free training though YouTube. You just have to search for it.
