Hi @erie-erie
I understand your requirement and the approach you’re considering via the workflow route because those are flat file sources. However, I believe that manual aggregation remains a task that requires administrative intervention, such as logging into ISC or triggering actions via API.
Using a file upload utility(SailPoint File Upload Utility 4.1.0) can eliminate these manual constraints and significantly reduce the administrative workload. By scheduling the utility on a server and using a task scheduler to automate the process, the job can be completed efficiently without manual intervention.
