Thanks for your reply Glen,
Hehehe , Your scenario will be easier for me.
I can´t change source data...but I can create new calculated measures(fixed,conditions,..), create extracts,.. thanks
If you can't change the source data, then I would suggest pivoting the data within Tableau as Shinichiro suggested.
This will have the same effect.
You are very welcome. I personally don't like to "PIVOT" data in Tableau side, but sometimes that's not under my control.
