Hello everyone,
I would like to access the value of a previous row, which of course can be done easily with the Analytic Query Step.
The problem in my case is that I need to access a value that is calculated towards the end of my transformation, whereas I need to access the previous row's value in the beginning. This does not seem to work, since all the rows seem to run in parallel and the field value of the previous row is not necessarily the final value the field will obtain.
A simple example transformation is show here:

Any suggestions on how to resolve this issue?
Thanks!
