How to deal with warnings in the import scenario?

I am trying to import fixed assets from a SQL Server database. I have setup the asset classes earlier, so I think the defaults from GL accounts will be populated from the asset class. 

When I run an import process, I am getting a warning message “Only GL Accounts will be changed, all other parameters remain unchanged Do you want to continue?”. I know in the UI it is possible to click “yes” or “no” to this warning, but how do you do that in the import export scenario?

I have attached my import scenario in this case. The error / warning message is in the picture.
