There’s no setting, it’s a flat default value, but we’re going to change that for 22R1.

Most of times Earliest start is the first working day of the planned week and Latest Finish is the last working day of that week (unless duration is too big and shifting it to next week)

This behaves differently for some scenarios when PM Interval unit is day.

Hi Djedai,

There is no such way to define it in the system. We can manually enter dates for that field according to our maintenance work. This could be according to an agreement with the customer, or that the object to be worked on is not available until this point in time. Most of the customers are not using this functionality according to my observations

Thanks & Best Regards,

Nipun
