Sort in the Transformer failed

[elavenil]

Hi,

Parallel job was created in DS 6.0.1 and we are in the process of migrating our projects into DS 7.1. While doing the migration, we encountered the problem as follows.

index arg (2) exceeds count: 2

Let me explain, what we have done in the job, the job reads data from dataset and sort the data using 3 key columns while loading the data into the output dataset and this job failed while running the job. But when data is sorted using 2 key columns, it is working fine.

Can anyone help me how to set index argument for a job/project?

Thanks in advance for your help.

Regards
