There should be some simple method or direct function available for sure, which Iam not able to find it readily. I can always go with If-Then-Else. But wanted to check, for other optimized options.

If there is any negative number, I expect 0.
Any positive can be send to the output directly.

Eg:

-2 --> 0
3 --> 3
0 --> 0

Thanks!

If-Then-Else.

You can refer to Parallel Job Developers Guide documentation - Appendix B - Transform functions for searching the functions available in DS , Its easy to search use Ctrl+F and then search...

There's a neat way of solving this with a server function:
but I'm not aware of an equivalent parallel function, so would recommend If..Then..Else for parallel jobs.

Neither am I, hence my response.
