Fiscal Variant

Can someone help with 2 basic questions:

1. What is 0FISCVARNT

2. How do I include it in my queries? I don't see it listed under the 'Time' dimension when building the query on the 'Customer' cube. WHen I look at the queries that came with Business Content (0SD_C01_Q012), I see fiscal variant being used - but I don;t see it under the 'Time' dimension.

thanx.
