#Fields & Relationships0 debatiendo

Hello, 

I need to find all cases that have had their status at 'on hold' at any time during the previous month - is there a way to do this? 

Status' do change frequently so running a report for all on hold cases won't capture those that were on hold last month...

Thanks,

I'm building an app for a youth camp, so there are children, parents, teachers, volunteers, staff members and others involved.

Is it best practice to use the contacts object only with multiple record types or a separate object for each type of person?

If I use a separate object for each, which type of relationship should I house in the Contacts object? Or do I just pick one and it doesn't matter?

I'm doing some practice tests for my admin exam and am a bit confused about the lookup field.

One record is "student" and the other is "enrollment". For every student account, there can be various enrollment records.

Which record do I create the lookup field on to track enrollment for each student?

I selected: Enrollment lookup field on Account, but the correct answer is Account lookup field on Enrollment.

Can someone explain how I know which record to put it on? Thank you!

Ok Rookie in Trailhead Playground. I'm trying to add a field in Object Manager Contact. When I select New in Fields & Relationships nothing shows up a new field to select. Probably something I'm missing on day two in on the trail. But any help would be appreciated.

A standard field (Industry) has disappeared from our Opportunity Fields & Relationships and Page Layout options.  Any ideas why and how to get it back?
