Ahsan/Navin,

The question primarily revolves around dimension tables and incremental load. If we take out SCD1/2 out of the scene for now, could you please answer Yes or No for the below questions? Please it is kind of urgent as the client is really worried about these aspects of data transfer in incremental loads. As always, appreciate your quick response. Assume that first full load has been done.

1. If we change a key field (effective date) of an account that does not have a new transaction associated with it in the ledger – will the change come over after an incremental load?
2. If we change a non key field (title) on a prior effective date of an account that does not have a new transaction associated with it in the ledger – will the change come over after an incremental load?
3. If we change a non key field (title) on a prior effective date of an account that does have a new transaction associated with it in the ledger – will it reflect after an incremental load?
4. During a load process Full/Incremental, dimension tables get loaded first right? IF not, and facts are loaded first, wont they error out seeing that no associated dimension details exist?
5. We have a few custom tables which dont have any sort of a datetimestamp columns. Is bringing them all over everytime load happens, the only option? What is the best method to handle these kind of situations?

Thanks,
Dan
