DSXchange

I would like to handle exception in build ops. If any exception the abort the job with custom error message (similarly like calling DSLogFatel function in basic routines).

I have seen "failstep()" macro in ds documents. Is this macro accepts the custom error message?.

Posting on the parallel forum would have been a good first step.

You can download the Orchestrate v7.0 manuals from Ascential Developer Net - among these is a manual describing all the operators.

Or, if your C++ is good enough, you can set up your own signal handlers. All exceptions are notified by signal. If you do take this route, make very certain that you preserve and reinstate the DataStage signal handlers - these are not the operating system's default signal handlers, and you can break the product by not doing so.
