Hello Henco, Zhang and others,
did you try killing the corresponding job process? Please refer to note #2059084, which asks to kill the process (for another purpose, but it still valid). Then restart CRR_CONTROL.
Another know reason for the hanging/delay are the RSZ* tables, which belongs to BEx analyzer. They have a special delivery logic, which can take long processing when being copied online in nZDM procedure. Please use the very last version and patch level of SUM always.
Best regards,
Tomas Black
