Hi Guys,

For the above req. we can't use SCD 1 or 2 or 3.
Bcoz for scd1 it inserts the new record and updates the
updated record.And here we wont be having any updated
records only new records will be there.

So according to me,the best option for the above scenario
is go with Incremental aggregation.

Please let me know if you have suggestions regarding this.

Thanks,
James.

I think what u can do is u can create a mapping by using
mapping wizard and apply SCD 2 as in SCD u can get historic
data while in SCD one u can onlly get the latest data.

create a mapping using SCD 2
Give the source and target tables.
Give the fields on which u want to implement the history
logic and then just complete the wizard.

the mapping will be created which will have 3 Update
strategy transformation which is basically one for insert
only flow, one for insert and update flow. and one for
insert and update flow also the previous records available.

The other transformations presented in mapping are in the
below manner.

Source --->> SQ --->>> Seq Gen --->>>> Lookup (For target
table lookup)--->>>>> Update Strg (3 nos) ---- >>>> Exp
Tr ---->>>>>> Target table.

Hope this will give you the clear understanding. guys
please correct me if i missed some thing.
