Replicate ODP Datasources in BW

Hi,

I have to use the ODP Datasources in my BW on HANA system 7.4 SP5.

I do not have knowledge about the ODP datasources.

Can anyone please let me know the following:

1. What is the difference between ODP and normal ECC datasources?

    Which are better?

2. Can we create generic extractors as ODP datasouces?

3. How can we replicate the ODP datasources from ECC to BW?

Any inputs would help!

Best regards,

Sidharth Mishra
