Lock unsuccessful -> Update record again

What causes this issue?

To keep a consistent dataset in CO-PA, the system has to lock the
records you are changing when it updates the segment level (Table &V2&).
User &V1& is currently locking the record(s).

System Response

The program terminated, because the system had to wait too long for the
lock to be lifted. This error may occur when the system is overloaded.

How to fix this error?

Repeat the update.
