Dear Yuncui,
We have 2 notification emails as follows:
1. 1st mail to notify to whom related that the job to generate Payroll output file (Application) is successful or failed. This one is sent to Humanica and do you need to send Invista ?
2. 2nd mail to notify to Humanica team that Payroll output file is push into your sFTP successful or failed (Server).
If you think Invista don’’t need to get the notification for 1., should let me know.
