I have to blend the data from 2 extract file, by keeping one primary and another one secondary. I am not able to populate the data which does not join the key fields.
Do we have any work around for getting union of 2 extracts....
Pls help me on this, urgent help required
Performing a UNION on two different data sources is not really possible. It's been discussed several times before on these boards. The best / most robust solution is to have your data combined outside of Tableau is some sort of ETL routine.
