performance overhead

Hi,

I have a quick question.

There is part in the project where we need to update information in SAP which we gather from the user. I am getting a series of name from user and updating it. For that I am using insert statement. If user tries modify those series of name, I do delete first and insert again.

I am not sure whether it is a good way. Also my concern is whether there will be performance overhead for SAP through my way?

thanks.
