sql server - SSIS - Slowly Changing Dimension - Latest data only -


i have table 10 million records. in dire need perform type 2 data warehouse table , changing dimension populate table. easy part.

the hard part is, want understand how can have ssis package @ items items modified date 72 hours or less current date; cause package run second time around. can have changing dimension run off of view has filter in it. not want expire records not in last bunch of data.

is there tutorials including screen shots of can make happen smoothly? have searched , searched , have found nothing, pretty sure easy do.

the scd wizard generate "historical attributes inserts output" dataflow, pass through derived column transform, ole db command transform. last component expired records updated.

you can edit sql code in transform, or delete component , reconnect dataflow.
