Dear Harsh Vardhan Shrotriya,
The report to create scheduled invoice requests is scheduled to run at 02:00 UTC and depending on the time zone of the tenant it will run accordingly. You can find the time zone of your tenant in the Fine Tuning activity Time Zone. The run is scheduled to run daily and does not consider weekends or public holidays. We do not want any user intervention and the task needs to be performed automatically and hence it is set up this way and is not visible in the User Interface.
I hope this will answer your questions.
With kind regards,
Kathrin Dietrich
