We are hoping to integrate HCM to a custom EPM implementation using BI Publisher extracts from HCM, however to avoid having sensitive data files sitting on a server, we want to initiate the extract from a batch script which would do the following:

1) Initiate HCM Extract and download the result

2) Use EPM Automate to upload the file to EPM Cloud

3) Delete the file from the server

Is this possible?
