We plan to use Transaction CO19 to confirm Labor hours for Operations. Currently we are working in two shifts. Morning shift 07:00 – 15:00 with 30 minutes brake and Afternoon shift from 15:00 till 23:00 also with a 30 Minutes brake. A worker is working over several days on the same Operation but of course only for one shift per day. Means he start processing on Monday and stop processing on Wednesday. He also changes the shift next Month. Is it possible to set up time calculation only for one shift (07:30) per day without to start and stop every day? If we start processing on Monday and stop it on Wednesday it calculates 15 hours per day (both shifts).
