remove col and row in cross table of wizard

hi expert,

I have a question want study from you.

when we load data from a excel table. I don't need all column to qvw file, there have a 2 method for my understand.

first, remove column by transformation step in "File wizard"; second, just keep useful column name in load script.

what's the different or not? my focus on if well impact memory in qvw or load efficiency.

thanks a lot!

Hi Kevin,

If  you take required columns  then it will improve your performance because its in memory tool.  Its Store your all data  on server memory means less data less memory.

Thanks,
