Can we delimit periods in custom tables

Question

Hi All,
I have a requirement wherein i need to create a custom table with following fields:
1) Company Code        - Primary Key
2) Fiscal Year              - Primary Key
3) Cost Element Group - Primary Key
4) Partner Activity         - Primary Key
5) From Period
6) To Period
7) Labour Rate
8) Material Price
Now I need the values something like this:
DC10    2001    Fringes    D1090   1   2   2.00   4.5
DC10    2001    Fringes    D1090   3   4   1.5     5
So its something like for the same set of first four fields, i may have diff rates for diff periods.
Is there any way to achieve this, other than making 'From Period' and 'To Period' as primary keys?
Thanks in Advance
