Hi everyone,

We need to schedule the process "Import Costs" to run daily, however we have 89 Business Units. With 5 different transaction sources, that is a total for 445 processes to schedule. In this context, I have 2 questions:

1. I would like to create a job set that runs 89 Import Costs processes in parallel each for a different Business Unit. I have been following the this document 1560915.1, but I can't seem to figure out where to specify the parameters for each job I'll be adding in the job set. I extracted the parameters used on an individual process from ESS_REQUEST_PROPERTY and none of them are available in the job set screen when adding a System Property. Where and how do I specify the parameters to use when running this job set?
