DSXchange

Our jobs are using Runtime Column Propagation.
What I need is to dynamically analyze the incoming layout and if the field data type is Date or Timestamp, then do some logic for each of those fields.
I am thinking of Custom Stage, but I do not know the functions to access the incoming layout information and build the logic on it.
Or maybe there is other method?

A custom operator would fit the bill. The Custom Operator Reference document will give you a lot of information. Here is the version for IS 8.7. You can also Google/Bing/whatever for it for other releases.
