Hi Oliie,
How is your recipe app setup? How do you start it? We need to know more to see how it can be auto-restarted.
Meanwhile, you can take a look at the Sequencer Object. This Object lets you cycle through different states. Maybe you can use this to cycle (restart) your recipe app.
Also, the DataTable Object in Lookout may be of interest to you. It is kinda like a super-set of the Recipe object -- it can do everything that the Recipe Object does, plus more. You can programmatically import Excel data, use cursors to traverse the cells, and so on.
Anyways, more details would be needed to answer your query more specifically.
Regards,
Khalid
