If SLT is using real-time replication data then it is continuously checking the logging tables for new records.
There are the ways for customer can reduce the number of the calls to the source system.

1. Need to Change the real-time replication to Interval.
If required change the LTR Settings, where the customer can specify the time in minutes, hours, day, the frequency to check the logging tables on sap system.
Perhaps once per minute is enough. Only issue with this is latency will be increase, having up to a minute of latency in the time the record appears in Hana target.

Change the logging table check behavior. In LTRC-> Utilities-> Specify Option for Logging Tables,
The another option is available for Process Logging Tables with Records will avoid querying the logging tables when they are empty and this is best option for logging tables.

How to check the Error Logs in SLT:

• Log into SLT system
• Execute the transaction LTRC
• Enter the your MT_ID and Execute
• Click the Application Log Tab then filter the ID and table name for error overview
• Check both system logs for the Source & SLT system
• Check the SM21 logs
• Check ST22 logs for analysis
• Check the WP logs in SM50

Validate Record Counts on Source R/3 System or Hana db level:
SAP SYSTEM:

• Log into SAP SYSTEM
• Execute the Transaction SE16
• Put in table name and execute
• Click on Number of Entries details.

HANA System

• Log into HANA Studio
• go to the Table in HANA
• Right click on table and click Open Definition
• Click on the Runtime Information

Compare the both system no of the logs
