Questions on replication from non SAP source to SAP HANA

Hi All,

I have a couple of questions that I hope you can help me on. We are currently replicating from MS SQL to SAP HANA using SLT. My questions are as follows:

1) Is it possible to only replicate changes to a specific column and not replicate all the columns? I know this might cause inconsistencies but just a question posed by a developer using SLT on our company. My answer is it is not possible but someone might be able to answer if it is possible.

2) When I add a column in a replicated table from the source (SQL). How do I get this change pushed to SAP HANA? Is there a way to automate that? Or do we need to manually change in SAP HANA?

Thanks and hope to hear from you soon.
