Factory calendars, non working days and planned orders

Question: Hi,

I have a problem where by you can assign one calendar per plant. The issue is we want to be able to create planned orders to begin on any day of the week, however we only accept goods receipts of externally procured materials Mon - Fri. Essentially I want to be able to make every day a work day on the factory calendar, but block saturdays and sundays for deliveries (I don't want MRP to suggest deliveries on these days).

I was told on here in the past that I could go the other way, leaving Sat and Sun as non working days, then have another calendar with every day as workdays, which I assign to the work centers that produce on weekends, however at time of planned order creation, these work assigned calendars are not used, and the planned order creation automatically moves the start date to the previous workday.

Does anybody have any suggestions?

Thanks,
Mark

Answer:
Normally, what you have done should work. It is same the method we use for our plants that run 7 days/week.

Do you have intervals inserted in your work centers making Sat. and Sun. non-working days?

Answer:
There is only one interval in the work center I was testing, and it has an indicator set to "Working days according to factory calendar".

From what I can see, and I could be wrong, the routing isn't even being checked when entering dates for a planned order. It seems like the dates are checked as per the factory calendar assigned to the plant, before it even looks at a routing.

Answer:
Are you using leadtime scheduling when running MRP? That should take your additional (or work centre) calendars into account for planned orders.

Answer:
We have an external planning system for the MPS side of things. We use i2 for all of our detailed planning and scheduling, and then we use SAP MRP purely for the purchasing of component materials.

I'm trying to create planned orders as per the production plan generated by i2 using a custom ABAP program. The same problem occurs as when trying to create a planned order using MD11.

Thanks for you continued help on this topic.

Answer:
Mark,

I'm guessing you have to hit the "schedule" button on a manual planned order prior to saving the order. This should perform leadtime scheduling.

I just thought of another thing. Check the order type planning parameters in config and check to ensure that you are creating capacity requirements. I could be wrong on this. I'm not familiar with using off line scheduling tools with SAP.
