There's incorrect behaviour when you try to modify some dates in Housing Placements.
You can Move In and specify the move-in date, but if you make an error, it's difficult to change. Yes you can modify the Start Date in the corresponding Housing History record, but the Move In Date on the HP record does not update.
When you Secure a Unit, you can specify the Housing Secured date. When you Add and Secure a Unit, you can't specify the Housing Secured Date
You can't modify the Housing Secured Date after the Housing Has been secured, in the case that a staff makes an error
Partially addressed in 4.0.60.5.1: "Fixed issue where the Date Search Started for Housing Placements could not be edited."
