Business impact if not resolved: This causes the Jobs not to be picked up in reports, causing mismatched data and a lot of extra manual work in order to fix reports 

Hi team, 

Fifa has reached out asking for us to provide a solution for this issue. They need to prevent users from updating the Job Categories, as this is causing them a lot of extra manual work in order to fix reports. When troubleshooting the ticket, I thought about using the User Groups to restrict the access. However, when other users access the Job, they can still select the category that I had previously restricted. I am raising this issue here as I'm unsure if I'm having the incorrect understanding of the functionality, or if this is in fact a bug. Kaleena Perkins has also checked the issue and she also believes this could be a bug. Could you please check and advise? And, if this is the expected behaviour, could you let us know if there is any other workaround available in the system or if this should be added as an enhancement request? 

Many thanks!
