Hello,

1)openning date (creation date) of the requisition 
2)approved date of the requsition 
3) closed date of the requsition - when it was closed / filled 

I tried to find those fields under the requisition fields (Configuration > Taleo Recruiting Administration > Requisition Fields) in Taleo
but wanst sure .

how can i find those fields to have them displayed .
see attached file - the fields in requisition.

Thanks ,
