Hello, 

When trying to get into the 'Candidate selection workflow' and to check the offer steps and activating them in order to create the offer it looks like they are unavailable . 
Currently in order to create an offer, i go to the 'Offer' tab under the recruiting tabs, and there press - more actions -> create offer- and manage . 
I tried to add the offer steps and statuses in the build in taleo offer step - under the configuration -> recruiting -> candidate selection workflow . but it looks like the offer steps and statuses and not available. The available bottom is disabled (see screens attached)
