LT Error Keeps bugging! Please Help!!!

Question

Hi,
We do have a Solution Manager with NW 7.02, where we instaled LT server in separate server scenario (DMIS 2010_1_700: SAPK-91704INDMIS 004). The same was installed at IDES 6.0 also, which acted as out source system. Both successfully connected to the HANA. Replication worked fine for few tables, for few days...
Then we decided to upgrade HANA to SPS03. We also upgraded LT to: (DMIS 2010_1_700: SAPK-91705INDMIS 0005).
The trouble started. Replication stopped.
Then we also implemented the SAPK-91705INDMIS at the IDES, where it is imported sucesfully (though it does not run LT server on the source system itself.)
When ever we create a new configuration schema for LT: the dynpro dialog raises an error:
Error occured when openning db connection
Verification of Schema failed due to connection issues
We deleted the three things to correct it:
- the LT Schema from LT server
- the user schema for replication users from Studio
- entries into the the tables of SYS_REPL_
However, the error still persists, and a big stopper. The RFC destinations working fine.
Please assist us on this. Many thanks in advance...

Answer 1

The 4 tables are empty.
Interestingly, the dev_w4 log contains a statement, which is failing when populating the tables of SYS_REPL.RS_REPLICATION_COMPONENTS. Is the table structure outdated? Our HANA is on Rev.21, where this table contains 12 columns.
The insert statement in dev_log contains only 9 fields:
INSERT INTO SYS_REPL.RS_REPLICATION_COMPONENTS (
SID,     CI_HOST,          SCHEMA_NAME,     PORT,     TARGET_SCHEMA,     PDB_NAME, COMPONENT,     SLT_SID,     SLT_HOST )
'ID5',     'IN-AIR-SAP7_ID5_00',     '',          '',     'HANU_MAN',     '',     'SLT',          'SM1',          'IN-AIR-SAP2') ;
Prima facie the table structure seems different in SLT vs. HANA system. Thats why the insert error?
FYI, both; the SLT, as well the SAP Source system runs SLT: DMIS 2010_1_700 SAPK-91705INDMIS, i.t. SP05.
