Data being dropped after joining Fiscal Time with Fact Table

Question

Hi,
In my RPD, i have jolined the Fiscal Calendar with my fact tables : Fiscal Day is joined to Create Time column in the fact table.
Fiscal Day Data is : 6/6/2006 12:00:00
Creare Time Data is : 6/6/2006 11:45:49
6/6/2006 11:56:50
When i pull the fiscal day column with the other columns fromthe fact table in the report, i only see a subset of my data. I beleive this is due to the timestamp and it is causing to drop records.
Is there anyway, i can join this and not drop records due to the timestamp.
ANy suggestions will be appreciated.
Thanks

Answer 1

I assume that fiscal day table is at the day level. I would suggest that you store the date in an integer format (for example 20060606 'YYYYMMDD') similarly you may store the creation_date_key in fact table which is also in the same format, then do a direct join. This will be provide good performance for your reporting since you are joining integers and not date or char formats.
If you want time of creation date also, you might want to store it in a seperate column in say HHMMSS format, this when joined with time dimension will allow you hierarchical reporting for time too.
