I want to be able to enter the start time for a piece of equipment when I start using it and then enter the end time when I stop using it. I then want to use this elapsed time as my machine time confirmation. I also want to be able to look at the piece of equipment at any time and see the current elapsed time. For instance, I start using X on 5/17/17 @ 01:00 and stop using 5/18/17 @ 13:00. On 5/17/17 @ 01:00 I enter this date and time and then on 5/18/17 @ 13:00 I enter this date and time. Now I want SAP to list the elapsed time for X. I hope this can be done, it will make the entire plants life much easier. Thanks.
