0RecordMode, ODS and Generic Data

I have created a Generic Datasource in R3 from a Y table.

I will not be doing a generic delta on it.

I replicated the datasource to BW and activated the necessary Transfer & Communication Structure.

Now i want to store all the data in an ODS, but when i try to create Update rules for the ODS, it says 0RecordMode not found.

I dont want to use delta and hence the help says i can do without it.

But still I am not able to create update rules.

Kindly help
