Basic dates in production order (scheduling, adjust basic dates)


I would like to schedule production orders by changing schedule dates. But in the same, I would like that basic dates are not changed (especially end basic date) and would like to keep original values.

The setting 'do not adjust basic dates' simply does not work in this way. Did anyone achieve that?

To be honest I think its even a bug in the system that when you go to order>scheduling you can not save the scheduling settings (adjust/not adjust). When you enter production order again it comes back to original settings from order type and your changes are gone.

    In OPU3 scheduling parameter of production order and plant, here set Scheduling based on Production dates.

    If the indicator is set, you must enter one or more production dates (scheduled dates). so basic dates will remain unchanged.

    It's not helping unfortunately. It makes scheduling dates 'active' but when you change scheduling dates, basic dates are changed again.

    My system is 6.0 EHP4.

    • Hello,

      The basic dates are calculated according to the in-house production time set on the material master of a product.

      You should make sure that the in-house production time defined on the material master is as close as possible to the times defined on the routing, so that the basic finish date matches the production finish date. Transactions CA97 or CA97N can be used to update the in-house production time with the information from the routing.

      You can define in ECC transaction OPU3, scheduling parameters for production orders for the relevant plant/ordertype combination, deactivating "Automatic Scheduling" and "Adjust Basic dates". Whenever the order gets saved, a scheduling would not happen and the basic dates would not be adjusted according to the scheduled dates.

      Best Regards,
