Retain Function in Data Intergration studio 3.4

[Sean_Milligan]

Good Morning,

Just wondering if someone can help me, i am trying to replicate a Retain Statement in DI studio, but i am struggling to find a method, i am simply wanting to create a new field which holds a value from a field already existing on the previous line,

for example:

retain ret_bal_cu ret_bal_pl ret_cls_dt amal mth_closed;
by pl_accnum pl_open_dt;

if first.pl_accnum and first.pl_open_dt then do;
ret_bal_cu=.;
ret_bal_pl=.;
ret_cls_dt=.;
end;

cu_prev_bal=ret_bal_cu;
pl_prev_bal=ret_bal_pl;
prev_cls_dt=ret_cls_dt;

ret_bal_cu=cu_curr_bal;
ret_bal_pl=pl_curr_bal;
ret_cls_dt=pl_cls_dt;


Can anyone provide any help?

cheers!

Hi

I believe you would have to implement this with a "user written code" node.

... and if it comes to this then it's always worth asking if there is also another way to achieve the final result you need.
