What is the difference between SLT and SDI?
Nevertheless, SDI comes second with almost equal number of transform options available to integrate and cleanse data. While the tool as such has a long way to go, it may acquire new transform options with each release. SLT, on the other hand, has very minimal transformation options that can be done only through ABAP.

Add the table again, Data Provisioning --> Provide the table --> Start Replication. This would create triggers/logging tables and replicate the table again.
What is logging table in SLT?
Logging tables are created by the source system for every table to be replicated. During the initial load itself, SLT identifies changes on source using database triggers, saves changes to logging tables and writes them to the target when the initial load is done.

How does replication work in SAP HANA?

Once system replication is setup between the two HANA systems, one is defined as the primary system and the other being the secondary system.
What is replication in data storage?
Data replication is the process by which data residing on a physical/virtual server(s) or cloud instance (primary instance) is continuously replicated or copied to a secondary server(s) or cloud instance (standby instance).

What happens after data load?
After data load, Status will be changed to “Executed”. The table will be created in “SLTECC” schema with data.
What happens after SLT load?
After the initial load is complete, SLT continues to monitor the tables in the source system and replicates data changes (also known as delta data) in the source system to the target system in real-time. As long as the SLT system is functioning correctly, temporary downtimes of the source or target systems do not result in the loss of any business data. If the target system were to become temporarily unavailable, SLT continues to record any changes to the source system in the log tables, and updates the relevant target system tables when the system is back online.

How does SLT work?
SLT loads existing data or a defined subset of it from the source system to the target system (the initial load), and the source system sets up logging tables for each table to be replicated. You can run the initial load of data while the source system is active. In parallel to the initial load, by means of database triggers, SLT detects any data changes that occur while the initial load process is running.
What is SLT in data replication?
