FixVersion Report with Release Date and Prior FixVersion Release Date

Hi @Speedydgon ,
You can take an idea from here on how to create the measure you are looking for:

To get the prior date you need to add -2 in the formula:

ChildrenSet([Fix Version].[Ordered release dates]).Item(
   Rank(
  [Fix Version].CurrentMember,
  ChildrenSet([Fix Version].[Ordered release dates])  
)-2  
).get('Release date')

In the report it looks like this:
