0 - 2 of 2 tags for data transfer from Table to another table

Hello
I copied some smaller tables from production to test environment. The problem is the usage of over 60 session for this job, which is blocking other production jobs.
Is there a way to limit the number of sessions for data transfer?

Folks,
I have just stepped in Teradata world.
Have a query on Fastload.
1. Can Fastload be used to Transfer Data from Table A to Table B [Empty table]?
2. If yes, does it need to use the INMOD functionality to read data from Table A?
