The easiest way to do this might be to create a filter in the Universe (UNX) within the IDT tool.
Here are some high level steps:
1) Edit the Business Layer of your universe and add a new Filter
2) Use something like the following in the WHERE clause of the filter:
convert(DATE, table.dateobject) = convert (DATE, {fn CURDATE()})
3) Save the filter and use it within your Webi documents that you want to filter on the Current date.
You could also edit the SQL of your Webi documents and customize the Where clause to include a similar Where clause that filtered on your date dimension.
For SQL Server, I used CURDATE() to get the current date, for your database, it might be a different DB function. You'll have to check your documentation.
Other than that, there isn't an out of the box way to do this that I can think of. I know there have been a few ideas (enhancements) submitted around this here:

I'd recommend finding one that matches your need and up-voting it. Or adding a new idea if you don't find one that fits your needs exactly.
Thanks
