How to add this filter?
Also why not use show selection then filter
Go to Solution.
Go to SYS00 module, create a Months only Filter. Apply that filter in the DEM01 Module.
As far your other question is concerned, we don't use Show, hide or select levels to show to achieve this because of two important factors
1. That is manual
2. Synchronization might not work with the dimensions
Hope that helps
