How to do Weeks in the Month

Dear all,

I have data e.g. Dealer, Car, Month, Amount.

My single record data looks like this 12345, HOLDEN, 201308, 50

I need to dynamically work out the weeks in the month, e.g. 5 weeks for August 1013, to end up with this.

12345, HOLDEN, 201308, 10

12345, HOLDEN, 201308, 10

12345, HOLDEN, 201308, 10

12345, HOLDEN, 201308, 10

12345, HOLDEN, 201308, 10

So I need to spread the months KPI over the weeks within the month.

Unfortunately the M_TIME_DIMENSION does not have this measure. SAP, would be nice if you could include this.

I think it may be done with some smart calculated and restricted measures

Any SQL gurus that can help me write a view over the M_TIME_DIMENSION, that I can use in a join, too.

thanks in advanced
