DSXchange

i am passing values to start loop from a comma delimited file.
it runs well till the last value and aborts while processing last value.

any thought on this

What error message does it throw?

Is there an output link (unconditional trigger) from your EndLoop activity to "the rest of the job sequence"?

job sequence design looks like this

command activity -->start loop-->job1-->end loop

i have a filelist.txt --> file1.txt,file2.txt,file3.txt\n
in command activity ---> cat filelist.txt
start loop activity mapped to command output
job1 input is mapped ---> start loop counter

file1, file2 processes fine but when it comes to third iteration file3 it fails with the following error
<sequence_name>..JobControl (@<job1_stage_name>): Controller problem: Error calling DSSetParam(<input_file_paramter_name_of_job1>), code=-4
[ParamValue/Limitvalue is not appropriate]

sorry for not putting a proper readable code

You've specfied comma as the delimiter, and DataStage is finding \n character. You can not have the \n character here. Or have all \n characters; specify it as the delimiter, and use ls -1 to get the list of file names.
