Remove Document Map (Report Service)

Recently I am working on MSSQL Reporting Services... when I print my report in excel file, I found something very annoying... a worksheet called "Document Map" automatically generated into the report... damn it... how to remove it!!???

Solution:
Open notepad and drag in your report.rdl file and then look up tag, remove the whole line, save it and that little shitty document map will be gone ;)
