ETL using Informatica 10 into BW 7.5 - DataSource creation BAPI error

Hi,

We have pretty latest environment and ran into this problem which seems to be a standard problem in BW 7.x versions while using Informatica as ETL tool.

We are on BW on HANA 7.5 SP1 and need to use Informatica PowerExchange 10 to load non SAP data into BW system. System does not let us create a Informatica type DataSource with below error message.

DataSource <ZINFA_ETL_TEST>(<Informatica>): Object type RSDS not supported in BAPI source system

Can someone help with any pointers if you ran into SAME problem.

Note - We are aware of 3.x process (using InfoSource for Informatica) and aren't looking for that. Attached is error message.

Thanks

Ashok
