Resolution Steps：

2. Follow the common recommendation for all the CO month-end processing transactions:
- During period-end closing, the system will select all the production orders in the system unless the deletion flag has been set on the orders. Please check if you can set deletion flag on any of your orders The most efficient way is recommended to set deletion flag to the orders which are not used or not relevant for processing. This will save a lot of time.
- Please consider to limit the selection via program RKO7CO88. You can split the current job into small packages like execute each order group with a new single job.
- Please check note 309588 for more information about object selection in period end closing and see if you can reduce the selection.
- Please review SAP note 393686 for more information on how to improve the performance of period-end closing including settlement.
- Check the details of SAP note 38855 Info on settlement: Performance improvements
- Parallel processing can be considered basing on SAP Note 386508.
After the above steps are exeucted, the performance should be improved significantly.
