Please check out this post in the Tableau Community on connecting to OBIEE from Tableau.
Hope this helps!
Things you need to consider when you think of OBIEE to Tableau migration.
There an object called RPD in OBIEE where you do all the data modelling, this can be complicated modelling most of the times. so I would suggest to start with the same.
- Look at the subject area of OBIEE
- Understand how complex the modelling is
- Its not a good idea to replicate the same modelling, Check the possibilities of creating mixed view at your source.
- Create the visualization based on that.
Check if you have any BI publisher component is there in your catalog. For this data modelling can be done at xdo files level.
Please make note of these things before you start the actual migration.
