Hello @LearnByMistk,
indeed, command line has preference as @Kurt_Bremser mentioned.
However, and towards make administration and maintenance easier, also to developers, my main recommendation would be to just create additional SAS Batch Servers on your SASApp. You can have as many as you want to, since it is not an IOM server. And on each Batch Server, you can select the memory settings. The configuration and autoexec can be either the same or you can make changes, as those memory settings.
On that way, the users will just need to select the right batch server when they deploy/schedule the jobs and it will automatically take the settings.
