Can you remove the number of openings field from a requisition form?

Content (required):

Our business wants to remove this field because they only allow 1 hire on each requisition, so number of openings has to always be 1 but they want to prevent users from entering anything other than 1.

I want to be sure the req will still be filled when we hire the candidate. I tested this and it did work. I removed it in test and hired a candidate and it did fill the requisition. But is anyone aware of any impacts to removing this field? I didn't find anything in Oracle support site.
