I found this note :1933605 which deals with the system copy (please refer to this link for more details:
System copy/refresh scenario comprising SLT replication to HANA)
... And there is one magic Z program embedded: ZMM_DEL_LOG_TAB ....
Does this mean that when we stop a replication to restart it later on (from scratch), SAP does not empty the logging tables?? (I have tested and it does not!).
The point is that the old info stay in the queue and are being kept even if the initial log is passed and written in the target system!
Of course the standard functions in IUUC_REMOTE and this above program do not work at all! I have no possibility to clear the logging table this is just crazy! SLT just replicates millions and millions of old records already logged!
Now I really help to understand how I can clear the data from logging table!
Thanks.
