Hi K,
As you are getting error in the initial stage and no tables are loaded/ replicated, i think it is better to remove the configuration in LTR and delete the user with schema name in HANA studio with cascase option.
Then retry with creating new configuration.
Also please be make sure do you really want to use "Allow multiple usage" and "Read from single client". If your use case relevant to 1 to N systems?
