Query Builder_Retrieving Comments field in a Variable

HI,

I am working on query builder in Windchill 10.1 . I need to retrieve the "Comments" variable as a column in the Report which will be generated.

The object which is routed for approval is : Change Request object. I need to retrive the Approver's comments and display it in the Report column.

Any help will be highly appreciated.

Thanks and regards,

Shweta Joshi
