Minimum wait time issue in operation

Dear Experts,

I have maintained the following setting is routing, but i am getting incorrect minimum wait time results in scheduling. It is getting as 2.50days instead of 4 days:

Product A

Base qty = 200 units

Operation Nos: 10, 20, 30 and 40

Operation 10 minimum wait time maintained as 24 hours

Operation 20 minimum wait time maintained as 24 hours

Operation 30 minimum wait time maintained as 24 hours

Operation 40 minimum wait time maintained as 24 hours

    • True. Wait time is scheduled in the non-working days/time also. In the calculation above, where Wait time falls in the work day/time is highlighted (For ops 1 and 4 the wait time comes into picture for 6 hrs each respectively during work day timings) and this is considered in the scheduling calculation.

      Outside of this the wait time is still scheduled. Routing scheduling using CA02 does not show all the details and that is why i said the easiest way is to create a production order for your material F-T0015/1215 and look at the details.

      FYI when you try to create a production order, you will see that the wait time for First operation is between 23/11 18:00 hrs till 24/11 18:00 hrs and similarly for last operation 28/12 18:00 till 29/12 18:00 hrs.

      23/11 18:00 hrs till 24/11 00:00 hrs is working and after that it is a non-work day and similar is the case for 28/12 18:00 till 29/12 00:00 hrs.

      Have a look at the screenshots of the four operations and the details of scheduling for more clarity and especially the dates/times at which Wait time is scheduled across the 4 operations.
