Answer / john

Generally we all knew that is,In Datawarehouse
environment,we should load data first in the dimension
table then we load into the fact table..bcoz fact table
which contains the Primary keys of the dimension table
along with the measures.
So we need to check first that whether the fact table which
you are going to load that has foreign key relationship
with the dimension table or not?If yes,Use pipeline mapping,
and load dimension data first in first pipeline and in the
second pipeline load fact table data by taking the lookup
transformation on the dimension table which has loaded data
already..and return the key value from the lookup
transformation then calculate the measures by using
Aggregator and also give "group by" on the dimension keys
and map to the Target(Fact) prots as required.
most importantly specify the "Target Load Plan"
where dimesion target as first,fact table target as second.
let me pls correct my answer If i am wrong..
