After the implementation of the correction note 1944811 some side-effects were observed by some customers.
The following simptoms can be observed on a production or process order confirmation on transactions CO11N or COR6N:
1 - When you click the button 'Actual data' the error message 'RU052 - The order header must be transferred for the confirmation' is triggered.
2 - The confirmation may be terminated with a short dump MESSAGE_TYPE_X of program SAPLCORF with error RU 888.
If you are observing one or both symptoms on your system, the following note should be implemented:
2020769 - CO11N: Program termination after message RU052 + determination of actual data
If you are observing errors related to the personnel number or if the error 'CO 469: Order [order number] is already being processed by [user name]' is triggered, the following note should be implemented as well:
2018945 - CO11N: Personnel number not saved in confirmation
