I have to rebuild table T604, T604T and /sapsll/clsnr, /sapsll/clsnrt in a S/4 HANA system with T604, T604T data out of a R/3 system. So I must delete the complete Content of T604 and T604T in S/4 HANA. But the delete doesn't work. I get always a SY-SUBRC = 4. The ABAP for this command is "delete from t604 up to 10000 rows." in a loop with a commit.
