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.

take a look t/f and a update strategy t/f. basing on look
up , if the record exits in target then reject it ,if not
exit insert it,and if the record exist but it is changed
then update it

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.

Answer / sasi
the best way to do this use the slowy changing dimension in
the mappings-->wizzard-->slowly changing dimension-->type1
here u need to select the source and target tables.

Hi, I saw one mapping implemented by my seniors . In Expression transformation they implemented following logic. That is iif(is_date(in_UC_DATINV,'YYYYMMDD'),to_date(in_UC_DATINV,'Y YYYMMDD'),'Inventory Date is either invalid or null') Inventory_Date is validated only for is_date() But not validated for notisnull() . But error says “ either invalid or null “ why? Whether is_date() also check for not isnull() ? or in this logic something is different ? Please answer me . Advance thanks
