Hi everyone, I have a suitelet that creates a time-entry and now I have to add this time-entry to a project but I can't seem to find out how I have to do this, can anyone help me out?

a time entry can be associated with a customer/project. The field

customer

is either your customer or project, it may be associated to a task or service item as well. Try to add a time entry manually in the UI to get a better understanding

awesome, thanks for your reply!
