Below is the scenario in which I have a question:

Fact/Measures Table with the following columns:

Fact_ID - Key - bigint
Document_ID - bigint
Version_ID - bigint
Item_ID - bigint
Amount1 - money
Amount2 - money
Document_Key - (Foreign Key - Document)

Dimensions:

Documents

Document_Key - Key- bigint
Document_ID - bigint
Version_ID - bigint
Payment_Date_Key - (Foreign Key - Date_Key)


Date

Date_Key - Key

The Fact Table contains multiple Version_IDs for a certain Document_ID. Each Document_ID->Version_ID combination points to a specific Document_Key in Documents.

I want to sum the Amount columns in the Fact Table in such a way that the Maximum Version_ID of a Document_ID is selected for a given Date Range.

How do I do that?

Thanks in advance for the help.

Hi and welcome to the forums. In order to help we will need a few things:

1. Sample DDL in the form of CREATE TABLE statements
2. Sample data in the form of INSERT INTO statements
3. Expected results based on the sample data

Please take a few minutes and read the first article in my signature for best practices when posting questions.
