  I have a situation in DWH where one of the dimension is not loading properly which is product dimension.

  The product dimension data comes from four oltp databases.so data which is coming

  from one of the oltp databases is creating a new record instead of doing a update for the already existing record.

  So for a same product id there are duplicates.

  the dimension is related to 6 different fact tables.

  Now i need the remove the duplicated dimension values in the dimension table

  and update the correct productid in the facttable

  I doubt you will receive many useful replies to your question unless you can provide something more concrete for people to work with.
