could not use RCP with checksum stage

[changming]

I try to build a common job to read any data set file and append checksum column and write the output into another dataset. In the source dataset file stage there is no column specified and I trun on the Runtime column propagation option.
when I run the job, the job aborted with error message :
PT_CombinedOperatorController,3: Failure during execution of operator logic.
can anyone tell me whether RCP can be use in such occasion?
thanks

Yes you can , when you choose the option "Use all colums" in check sum stage.

Thanks for your reply.
I did do as you said and job aborted before I asked this question in this forum. Can anyone tell me any tricky thing I have to pay attention to make it work?

No we can't. The job may have aborted for a completely unrelated reason. Please post the exact error message(s) from the aborted job's log.

Hi
the errors are
APT_CombinedOperatorController(1),1: Failure during execution of operator logic.
--repeat 3 times
APT_CombinedOperatorController(1),0: Internal Error: (!exportLog_->hasError()): checksum/checksum.C: 379
Traceback: Could not obtain stack trace; check that 'dbx' and 'sed' are installed and on your PATH
--repeat 3 times
main_program: APT_PMsectionLeader(3, node3), player 2 - Unexpected exit status 1.
--repeat 3 times
if the source is ODBC connector, the whole logic worked. it is just not working on datasets file.

Disable operator combination and run again, so that we (and you) can determine which stage, or operator, is throwing the error.
