Hi Irfan,
1st-- I don't think there is table in destination where we can maintain log
2nd-- SLT write the whole database table to HANA db, I don't think you can see the replication time in destination tables;
Reg : adding an entry log in the table this even I am not sure; but the replication time details will be available in SLT.
if the source is ECC system ; the log and trigger table and read module are created in source and you can see those in SLT server ;
If non-sap system then both table are created in source system but READ module will be available in SLT server;
Thanks,
Imran
