production order operation start and end date on non-working day

[Former Member]

Hi,

When an order is scheduled, operation start and end dates are being determined on a non work day even after factory calendar assigned to the respective operations identifies Saturday & Sunday as non-working days.

Please note that basic order start/finish dates or Scheduled start/finish dates doesn't have this issue.

Can you help in understanding this behavior please

I have referred following existing posts, but couldn't get help

Also I have referred following sap notes

2038668 - Non-working day has been set for production order 's start/finish date.

1895951 - Order dates and factory calendar

I have defined only one calendar and assigned it as both factory/work center calendar.

Also when i maintained the intervals & Shifts, operations are not scheduled on sat & sunday's

but, after this when I choose current date(19.07.2017) for both Forward/current date scheduling, system is changing the basic start date to 20.07.2017 & scheduled start date: 20.07..2017 time:21:04

So now I am stuck with

1. Why system is changing the basic/scheduled start date to tomorrow

2. Why system is considering the scheduled start time as 21:04, when as per work center start /finish time: 00:00:00/24:00:00 w/o any breaks

Not able to understand this behavior.

Hi Raghava,

You can check these settings again:

1. work centers assigned to the operations.
2. factory calendars assigned to these work centers.
3. if Saturday/Sunday are set as non-working days for the exact factory calendar.

Basic dates are using factory calendar in plant, but operation dates are using factory calendar in work centers.

best regards,
