In a mapping i have three dimensions. If i want to pass a
same surrogate key value to all the three dimensions by
using one sequence generator is possible?If the mapping is
containing single flow? And in the same case if the mapping
is contaning 3 flows for the three dimensions then by using
one sequence generator can we populate surrogate key (same
value) to all the three dimensions?

Answer / raj
Use the Sequence and Expresion transfermations.first
genarate the surrogate with Seq trans,then send values to
exp trans,connect the exp trans o/p ports to 3 dimentions.
First Seq generate the surrogate key like 1,2,3,4,5
we wil pass this column to next tran(Exp) from there we
will connect o/p port to dimentions.so '1' wil go all
dimentions,then '2' wil go then '3' .....

Answer / shankar mahadevan
Solution algorithm
1. Sequence Generator – generate the surrogate key
2. Expresion transformation – pass the (step 1) values
3. Connect Output port of (Step 2) to all 3 dimensions

Answer / sumana
Hi i have a samll doubt on this
Three dimensions are in same mapping but three different
flows. 3 diffrent flows means when the first completes then
only the second flow will start in this case by use one
sequence generator how will we pass the same values to all
the three dimensions. The surrogate key value should pass
like this for all the dimensions
dim1 dim2 dim3
---- ---- -----
1 1 1
2 2 2
3 3 3
4 4 4

Answer / uzval_vee
u can pass same surrogate key to three dimensions ,this is
possible in case 2 i.e 3 flows,according to my view

yes offcourse we can do it
for understandi this you can refer SCD2 version it haapens
same like ur qustion

Answer / phani
yes we can pass same surrogate key for 3 dimentions. bcz
three dimention are involved in same mapping. we can also
reuse the sequence generator.
