about Dimensions..
The Slowly Changing Dimensions Wizard creates mappings to
load slowly changing dimension tables:
Type 1 Dimension mapping. Loads a slowly changing dimension
table by inserting new dimensions and overwriting existing
dimensions. Use this mapping when you do not want a history
of previous dimension data.
Type 2 Dimension/Version Data mapping. Loads a slowly
changing dimension table by inserting new and changed
dimensions using a version number and incremented primary
key to track changes. Use this mapping when you want to
keep a full history of dimension data and to track the
progression of changes.
Type 2 Dimension/Flag Current mapping. Loads a slowly
changing dimension table by inserting new and changed
dimensions using a flag to mark current dimension data and
an incremented primary key to track changes. Use this
mapping when you want to keep a full history of dimension
data, tracking the progression of changes while flagging
only the current dimension.
Type 2 Dimension/Effective Date Range mapping. Loads a
slowly changing dimension table by inserting new and
changed dimensions using a date range to define current
dimension data. Use this mapping when you want to keep a
full history of dimension data, tracking changes with an
exact effective date range.
Type 3 Dimension mapping. Loads a slowly changing dimension
table by inserting new dimensions and updating values in
existing dimensions. Use this mapping when you want to keep
the current and previous dimension values in your dimension
table.

Confirmed dimensions
