Hi,

How can i add/remove columns from 'Requisitions' ' display and 'Candidates' display .
when going into the requsition  tab , and view the requisitions, there are some fields in the 'requisition 'Target Start Date' ,
'Target End date' that we would like to view in the columns as well.
see attached - for now we can view the : title,ID ,job code ,status etc. and would like to add columns .
Also in candidates to remove the 'ace' column from the display of all requisitions.

how is it possible please ?
