Fact Table and Slowly Changing Dimension

[dpietersz]

I have build a Fact table for a CRM system. See the image below.

I have two problems:

1. The field "Accountmanager" in the table "Company" needs to be a Slowly Changing Dimension (type 2)
2. I need to keep the history of every sales record to determine the average sales cycle

I found an example (see this thread) which I think I can use for problem 1. But I don't know how to implement it in my existing datamodel.

Anyone who can help?
