I am getting a version number,start date and end date. Now I want to populate the fact table based on the scd type2. What is the best approach for this?

Use the 'Dimension lookup/update' step for looking up the surrogate id ('Technical key field'), based on the natural key(s) ('Keys') and timestamp ('Stream Datefield'). Uncheck 'Update the dimension' if you only do lookup.
