If additional columns, Cost Center, Project, GL Code, Authorization and Comments are added to the request list, these columns are displayed, but do not contain the values from the requests in the list.
The values for these columns were removed as part of the performance tuning which was done for Service Catalog 17.1. The ability to add these columns will be removed once Service Catalog 17.1 rollup patch 1 is installed.
