SLT Replication in a NUTShell...!!!

1. Login to SLT Development Server – SAPBASIS / f2xxxx

2. Go to LTRC and select the appropriate Configuration – In our case, ECC_PRD is the config with mass transfer ID – 29 being used for data transfer from DEV/250 to HANA AXD ECC_PRD schema.

(SLT config name and target HANA schema will be same)

3. Ensure that you selected correct MASS TRANSFER ID and select “Processing Steps” tab

4. For every request to setup SLT table transfer, we need to process all the 5 steps in sequence without FAIL

Ensure the requested tables are updated on tracker link - SLT Tracker

Step#1 – Get the list of requested tables to be SLT’d and add it here

Execute it

Perform the same step through STEP#5 until “Runtime generation module”

5. Once all the steps are complete, proceed to trigger replication for these configured tables

6. Add the requested table list and select “Start Replication”

7. Execute it to trigger the real time replication for these selected tables

8. Once the replication started, switch to tab “Data Transfer Monitor” and ensure there is no “Load/Blocked” entries on column “Blocked Processing Step”

Once all the above steps are complete, confirm the requestor that the tables are configured for SLT.

How to Reset HANA System Password at OS Level (If you forget / someone changed).
