Hi Konata,
If your displaying date as headline(like key figure headline) then use below steps for 2014.09.01.
1 Create replacement path variable for year part use offset ex 2014
2 Create replacement path variable for month part use offset ex 09
3 Create replacement path variable for day part use offset ex 01
In headline select first replacement variable and then type "." or "/" and select second variable then "." or "/" and select third variable .
Please try this,.
Thank you,
Nanda
