SAP ABAP qRFC Name

[gagan8877]

When using DS 8.5 ABAP stage to extract data from SAP R/3 system:

1. There is a setting called qRFC queue name on the transfer Method tab (method = RFC). If you have 4 ABAP stages in 4 jobs to extract data, will you need to use different RFC queues in each stage to extract 3 diff tables? Whats the best practice?

2. If one stage/job fails (out of 4 running jobs in parallel) and you are reading from the same qRFC queue, will the other stages/jobs extracting in parallel fail too?

Any kind of help/suggestion would be wonderful.

Thanks
Gary
