Usage of  Procedure(Oracle)  is common to Populate Time Dim.

U may have diffrent Hier.chies but still for ecah level accordingly u need to use some date or time format.

Becareful while populating time data in dim table... Ofcource Procedure will take care of everything.....(Taking on input data and output date is important in Procedure)

Hi this would be the normal SP Code that i use to populate a time dimension,

well again it depends on the business requirements to know what level the Grain is required for a time dimension
