Hi All,
the root issue can be within Embedded Search or within your TREX environment.
For Embedded Search:
See SAP Note 1764978 - Error when activating ESH connectors without ODP
This is the bug and solved in NW AS 7.31 SP06 the workaround is to execute RODPS_ODP_IMG.
Still mentioned in this thread.
Or Embedded Search is not able to create the indexes on TREX side because there are already exists.
Workaround:
1) Delete all indexes via program: ESH_ADM_INDEX_ALL_SC
2) Check and Delete all indexes in TREXADMIN or the TREX-Admin Tool
3) Check and delete all indexes on operation system level
4) restart TREX demon / service
all of theses 4 steps must be done.
Best regards
Frank
