Add additional fields to requisition approval notification lines in R12.2.10

Hello,

We are in the process of upgrading from R12.1 to R12.2 and now notice that in requsition approval notification not all fields available are displayed in the requisition lines. Through Rich Table functionality we can show/hide/reorder a particular set of fields, but others fields like Cost Center are not available - although they are present in the data and page itself.

How to add this field to the table?

Thanks, Patrick
