Process simulation schedule question

Hello,

I have a question regarding process simulation – I am simulating airplane departures.

I would like to define process entry schedule, however I have an issue. When selecting „Date and time“ in Schedule model – „Manage recurrence“, I would like to specify dates for the event to occur within the single month.

For example, I select 3., 15., 20., 27. as dates within a single month.

However, simulation does not recognize this, and after running the simulation and checking these settings again, ARIS for some reason resets the parameters. Also, I select „Process Instantiation“ to value 1 each time, and after running simulation and checking the settings again, instantiation goes back to 0.

Thanks a lot in advance!

Regards,

Dino
