RTC- Column Display in a Query with the contents of the tab History of Defect WIs

I am using a developer-Token of Rational Team Concert vers.4.0 (Web Interface).

I kindly ask if you can set up a query with the addition of the columns contained in the Comments tab History of a Defect WI type, using the function Edit Query -> Column Display-> Add Column-> Select Attributes. Which is the right attribute to get the display of the contents of Tab History?

My aim will then be to export the query in CSV format using the "Download as Spreadsheet (. Csv).

Thanks for the support,  I cordially greet, Luisa Madonna

P.S. In detail, J ask what are correct information to give into the Administration page for my project area during the "Add Attribute" configuration (Name, Type , ID) ?

For example, are these parameters correct ?

Name= Comments Type =Large String  ID= com.ibm.team.apt.attribute.Comments
