Drill Back to Analytic Blend from Cube Data ???

In order to clarify the issue, let me know if anything I state here is incorrect:

- You have a CubeView MD adapter pulling data from a Cube View (hence cube data); you have a chart populated by that adapter

- You have some sort of BiBlend table. I guess it was somehow produced by the same Stage Data that ended up being loaded in the cube (?)

- You want to somehow link the two

If that's what you want, that's not a DrillBack, so let's drop that term.

There are a few different ways to go about this problem. If you want to avoid code, you could

1. populate some Parameters behind the scenes, to define the values you want to pass to a query on the BiBlend table;
2. create a Data Adapter of type SQL that uses those parameters in the query, e.g. SELECT * FROM MyBlendTable WHERE Entity = '|!MyParameter!|'
3. connect that adapter to a gridview

I suspect your issue is with 1, and solving that will depend on which components you are using. You say you have a Map, so I guess you used the BiViewer component...?
