Changing dataprovider from Unv to BICS

Hi,

I am planning to change dataproviders from UNV to BICS in batch. I am on 4.1 SP 5 (<build>14.1.5.1501</build>).

How to address the optional parameter on BW query. If I am not answering them it keeps on popping up when posting the proposal.

Any other known issues / best practices. Kindly share your thoughts.

Thanks.

Regards,

Subramanian S.
